The pilot safety relief valve is mainly used in oil and gas, chemical industry, electric power, metallurgy, city gas and other fields, and it is the best super sub protection device on pressure equipment, container or pipeline. The working pressure is allowed to approach the set pressure of the safety valve. Small overpressure can make the main valve quickly reach the full open state. The action performance and opening height of the safety valve are not affected by the back pressure. The non flow structure design of the guide valve reduces the discharge of harmful medium and environmental pollution.

Characteristic

The soft sealing of the valve seat ensures the good sealing before and after the safety valve takes off.

The working pressure is allowed to approach the set pressure of the safety valve.

Small overpressure can make the main valve quickly reach the full open state.

The action performance and opening height of the safety valve are not affected by the back pressure.

The opening and closing pressure difference is adjustable.

The non flow structure design of the guide valve reduces the discharge of harmful medium and environmental pollution.

The setting pressure of safety valve can be detected online.
