In-line Pressure Vacuum Relief Valve with Flame Screens
برای قیمت تماس بگیریدThe in-line pressure/vacuum relief valve is an automatic pressure/vacuum valve, which operates through the vapor header. It relieves pressure and vacuum during loading, discharge, voyage and ballasting.
In-line pressure vacuum relief valve is installed on cargo tanks, I.G. main etc.
The In-line pressure vacuum relief valve is a combined pressure/vacuum relief system, and it is designed for marine tankers and chemical tankers.
The In-line pressure vacuum relief valve is designed and constructed to comply with IMO MSC/cirs 677.
The materials for shall be selected for the stored-product service temperatures and pressures.

Pilot-operated PressureVacuum Relief Valve
برای قیمت تماس بگیریدPressure and/or vacuum relief valves are used for dangerous oil, gas or petrochemical storage tanks and other process vessels or systems to prevent structural damage due to excessive pressure or vacuum in.
Pilot-operated pressure/vacuum relief valves is performed best at applications, which is required high amount of backpressure or fluctuating backpressure.
– Opting for modulating pilots allows the piston to lift only as high as needed, venting off just enough pressure to prevent cycling (a common side effect of backpressure that can cause undue wear to valve parts).
Pilot operation is also recommended for equipment’s which low accumulation rates are required or when the set pressure level needs to be close to the operating pressure level.
– As pressure increases, the pilot maintains its seal tightly, allowing reliable operation closer to the set point for pack line without product leakage.
– Pilot-operated pressure/vacuum relief valves can work at an operating pressure of up to 98% of set pressure.
Although their initial investment cost tends to be higher, pilot-operated pressure/vacuum relief valves are much smaller than their spring-loaded counterparts, making them easier to install, maintain, and repair.
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.
