Surge Relief Valve Mechanical Stand-Alone Axial
برای قیمت تماس بگیریدcan be installed in places where it cannot supply power sources such as electricity or hydraulic pressure, such as underground or desert, or cannot be maintained, and can be used in sewage or high-viscosity crude oil lines containing foreign matter.
Surge Relief Valve Pilot Operating
برای قیمت تماس بگیریدconsists of a main valve, low and high pilot valve, and accessory, completely assembled and tested as a unit and ready for field installation.
SRV is installed in the bypass line pipe to protect the piping system from the surge (Water hammer) by sudden flow change and pump sudden stop.
Main Valve is opened when low pilot valve anticipates the negative pressure in piping system to prevent the pipe pressure arisen, and when high pilot valve detects the exceeding pressure in piping system to discharge pressure.
Main Valve is closed tightly when normal operation is in state.
Surge Relief Valves N2 Loaded Operating
برای قیمت تماس بگیریدSRVX is installed in the place that require fast response performance to protect the piping system from the surge (Water hammer) by sudden flow change and pump stop.
Model SRVX consists of a main valve, N2 bottles, plenum and accessories, completely assembled and tested as a unit and ready for field installation.
SRVX is stand-alone self-acting surge relief valve not requiring the external power. Main valve is closed completely when normal operation is in state.
When the pressure in the piping system exceeds the set pressure, it forces the surge relief valve to open and allows the excess pressure to discharge.
Response times vary in each application, the surge relief valve always responds rapidly and very smoothly.
Typical response times are milliseconds to full capacity.
Surge Relief Valves Solenoid Valve Operating
برای قیمت تماس بگیریدSRV is installed in the bypass line pipe to protect the piping system from the surge (Water hammer) by sudden flow change and pump sudden stop.
consists of a main valve, solenoid valve, air set, completely assembled and tested as a unit and ready for field installation.
Main Valve is closed tightly when normal operation is in state.
When an exceeding pressure in piping system is occurred, surge command from pressure transmitter operates the solenoid valve, and main valve is opened to protect the surge (Water hammer). It’s full opening time is less than 200 milliseconds.
SWING TYPE
برای قیمت تماس بگیریدSwing check valves are used to protect installations against black flow. They are entirely operated by reaction of flow and then do not require any external actuation.
Bolted bonnet is common for low pressure valves, but we can propose bolted bonnet for high pressure service.
Swing check valves can also be manufactured with a piggable design. They can be fitted with an actuator in order to block the disc in closed position. Or they can be fitted with a dash pot to reduce tilting.
