Slug-Control-Valve
  • Pressure Reducing Valve:

Automatically reduces a higher inlet pressure to a constant lower outlet pressure. The valve consists of a main valve and (Fig. 55) pressure reducing control pilot. Slight changes in downstream pressure acts on topside of control diaphragm causing main Valve to counteract pressure changes and hold a constant outlet pressure.

The regulator will reduce the upstream pressure to a constant downstream pressure regardless of the change in flow rates/or inlet pressure. The pilot is a Normally Open valve that senses the downstream pressure.

  • Pressure Reducing/Solenoid On-Off.
  • Pressure Reducing/Surge
  • Pressure Reducing/Low Flow By-Pass.
  • Slow Acting Check Valve:

Non return function, closes automatically in case of reversal flow. The valve allows flow when inlet pressure is higher than outlet pressure. In case of reverse flow, the valve closes within appropriate time to ensure it does not generate any surge / water hammer. Ideal for Air craft fuelling application. Valve opens and closes at controlled (adjustable) speed to ensure smooth flow.

  • Pressure Relief Valve:

Auto Re-circulation on a Refueller to control the pumping pressure of Air Crafts. Solenoid Override or Pneumatic Override to safeguard the system. This can be operated remotely to re-circulate full flow. When installed in Main line, it prevents upstream pressure dropping below preset value. When installed on a By-Pass line, it controls main line pressure by relieving excess pressure in By-Pass/sump. Ideal for pump by pass to protect the downstream equipments. Relief pilot (F22) is normally closed due to spring tension. With increase in upstream pressure above set value, Pilot (F-22) opens which makes Main Valve to open fully.

  • Rate of Flow Control:

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:

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.

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 de-energized 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.
