Pressure Safety Valve With changeover valve(single control)

Pressure Safety Valve With changeover valve(single control) is composed of one switching valve and two spring type safety valves in parallel, with the same inlet. By switching the device, one safety valve can operate and the other safety valve can be closed, and the two safety valves can take turns switching to the working state.

The switching device can be equipped with different types of safety valves according to the different media, temperature, and pressure used to adapt to different working conditions.

The inlet and outlet flanges of the switching safety valve can adopt national or American standards according to user requirements.

The safety valve should be installed vertically and installed at the gas phase interface position of the container or pipeline.

Pressure Safety Valve With changeover valve has more names as follows depending on what they are called:

Pressure safety valve change over system,Change over Valve china,Change-Over Valve,Safety valve with changeover valve

Features

◆ Three-way flow path design, one station is equipped with two identical safety valves, one of which is online for overpressure protection, and the other is used as a backup for maintenance.

◆ Fast switching without device shutdown, providing continuous overpressure protection, avoiding the costly loss caused by emergency shutdown and maintenance.

◆ The flow resistance is small to ensure that the safety valve has sufficient discharge capacity.

◆ The operation of the reversing system is safe, simple and fast.

◆ Below each safety valve, a relief valve is installed to safely and effectively discharge the medium before the safety valve to be disassembled.

◆ For high-pound class (≥600 lb), the quick-switching device is equipped with a balance valve, so the operation is light and convenient.

◆ Wide applicable temperature range (low temperature to high temperature).

◆ The seal is reliable, and it still maintains good airtightness even after repeated actions.
