Pressure Reducing ACV

Pressure Reducing Automatic Control Valve

BTA 511
Brightech™ manufactures a complete range of Automatic Control Valve and hence offers pilot operated pressure reducing valve, design to reduce higher inlet pressure (up-stream pressure) to a constant stabilized lower outlet pressure (down-stream pressure) regardless of varying of up stream pressure & flow rates.

This is an accurate pilot operated pressure regulating valve capable of holding down stream pressure of a pre-determined limit. The pilot reacts to a small changes in pressure to control the main valve position by modulating the pressure above the diaphragm and when down stream pressure exceeds the pressure setting of control pilot the main valve and pilot close drip tight.

  1. Pressure Reducing/Sustaining
  2. Pressure Reducing/Check
  3. Pressure Reducing/Solenoid On-Off.
  4. Pressure Reducing/Surge
  5. Pressure Reducing/Low Flow By-Pass

A hydraulically operated pilot controlled modulating type pressure relief valve is design to maintain constant up stream pressure and to minimize surging.

Installed on a by-pass line, mainline pressure is accurately controlled by relief excess pressure. This valve can be used for pressure relief, back pressure, up stream pressure control and many more.

Installed in a mainline it prevents upstream pressure from dropping (sustain) below preset minimum.

Rate of Flow Control ACV

Flow Control Automatic Control Valve

BTA 411
The rate of control, pilot operated valve maintain a constant flow rate adjustable, regardless of fluctuation in line pressure.

Function

The pilot senses the differential pressure across the specially sized thin edge orifice plate mounted in the valve inlet flange. when the pressure differential is less than the set point, the main valve opens and allowing to maintain the desired flow. At the desired max. set point the pilot valve reacts to small changes in sensing pressure and controls the main valve position by modulating the pressure above the diaphragm.

When the pressure drop (across) the orifice exceeds the set point, the valve closes slightly, limiting the flow to pre-set minimum.

The orifice usually sized to generate a pressure differential of 3 to 5 psi at the desired max. flow. Adjusting the pilot setting permits the max. flow to be changed in the field above or below the original point.

Booster Pump Control ACV

Booster Pump Control Automatic Control Valve

BTA 311-46
A Pilot (Solenoid) operated Booster pump control valve is designed for Installation on the discharge of Booster pump to control opening & closing on pump start up and shut down, eliminates pipe surges.

Function

The pump starts against the close valve, when the pump is started, the solenoid control is energized and the valve begins to open slowly, gradually increase the line pressure to full opening head. when the pump is signaled to shut off the solenoid control is deenergized and the valve begins to close slowly, gradually reducing flow, while the pump continues to run.

A three-way solenoid valve controls the valve operations equipped with hydraulic check feature to close valve on pressure reversal and shut off pump in event of pump failure. Valve and pump operations are interlocked by limit switch assembly.

Additional Features
  1. By-Pass Pump Control Valve
  2. Hydraulic Check Valve

Level Control ACV

Modulating Float Control Valve, Level Control Valve

BTA 111


Function

The model BTA-111, Modulating float control valve to maintain constant liquid level in storage tanks and reservoirs by companensating for variations in supply or demand, keeping the tank full.

Additional Features
  1. Non-Modulating Type Float Control Valve

Solenoid Control ACV

Solenoid Control Automatic Control Valve

BTA 311
Function

Operated by two way - three way solenoid pilot valve, BTA-311 a Solenoid Control Valve is an on-off control valve that either open or closes upon receiving an electrical signals to the solenoid pilot control, provides two position [ On-Off ] Operation. The main valve opens fully or closes drip tight depending upon the actuation position of the solenoid, energized to open/energized to close. The valve may be remotely operated by timers, relays, probes or any triggered device to the solenoid.

Additional Features
  1. Electronic Flow Control and Metering System (Dual Solenoid)

Hydraulic Check Control ACV

Hydraulic Check Control Automatic Control Valve

BTA 811



Function

It permits the main valve to be fully open when inlet pressure exceeds outlet pressure in the normal direction and main valve close drip-tight on reverse flow. Opening and closing speeds are separately adjustable.

Altitude Control ACV

Altitude Control Automatic Control Valve

BTA 721



Function

The model BTA-721-1, one way Altitude valve controls the high water level in elevated Tanks or reservoirs. The altitude pilot senses the hydrostatic head of the reservoir to close on high water level. When the water level drops below the predetermined set point the valve opens to fill the reservoir. Supply pressure is greater than static head pressure. Tank discharge is by separate line.

Working

This is a hydraulically operated and pilot controlled valve which operates on the differential in forces between a spring load and the water level in the reservoir. The desired high water level is set by adjusting the spring force. The pilot control measures the head through a sensing line directly connected to the reservoir.





Digital Set Stop ACV

Digital Set Stop Automatic Control Valve

BTA 311-66
Function

It is an electrically operated, electronically diverted, hydraulically actuated, diaphragm valve. The flow into and out of the upper operating chamber is controlled by the two-way solenoid pilot. The electronic control determines whether the opening solenoid or the closing solenoid is operated. The change in valve position is dependent upon which solenoid is operated and the duration of the energized period. The electronic control determines the valve function. Virtually any hydraulic function can be achieved using open-close output from the controller to the valve.

Working

The two way solenoid operate the main valve. The first connects the main valve inlet to the diaphragm chamber and when it is open, causes the main valve to close. The second solenoid connects the main valve outlet and, when it is open allows the main valve to open. A needle valve is provided in series with each solenoid, giving separate adjustment of the valve opening and closing speed.

Deluge Valve

Deluge Valve

BTA 1001
Function

Brightech™ Deluge valve is a solenoid control on-off valve which either opens or closes upon receiving an electrical signal to the solenoid pilot control to provide water flow to the fire protection sprinkler system. This valve consist of a Actrol  main valve , a three-way solenoid valve and an auxiliary pilot valve. This pilot control system alternatively applies pressure to/or relieves pressure from the diaphragm chamber of the main valve. it is provided either normally open or normally closed. pilot system can be hydraulically , pneumatically or manually operated.

Working

Energized the solenoid valve pressurizes the diaphragm chamber of the three-way auxiliary pilot valve. The pilot valve then shifts to relieve pressure from the diaphragm chamber of the main valve , allowing the main valve to open fully and admit water through the main line. The valve may also be opened by utilizing the manual override ball valve on the bonnet , which allows opening of the main valve regardless of solenoid pilot activation. The valve closes when the solenoid valve is de-energized.

Filter Separator Control ACV

Filter Separator Control Automatic Control Valve

BTA 221
Function

This model has a specific purpose; to shut off the flow of fuel to a pre-set maximum in response to a signal from the float control of a fuel-water filter/separator. it is a hydraulically operated pilot controlled, diaphragm type globe valve. The valve will close drip tight in case of diaphragm failure providing fail safe operation.

Working

The interface float pilot is down with little or no water in the sump of the filter separator. The float pilot routes vessel pressure to the bonnet of the three-way auxiliary pilot. This position the three-port auxiliary pilot to connect the bonnet to the main valve down stream, allowing the valve to open.

With a high water level in the sump of the filter separator, the float pilot of the interface pilot is up. The float pilot vents pressure from the bonnet to the three-way auxiliary pilot, shifting it to apply full inlet pressure to the bonnet to the main valve and drives the valve fully and tightly closed.
