Explosion Proof Wave Safety Pressure Reducing Valves For Avoid Water Hammer

Explosion-Proof Wave Safety Valve (FA49H) For Avoid Water Hammer

The explosion-proof wave safety valve can eliminate the water shock & prevent water hammer.

Installed in the beginning of the pipeline to prevent water hammer and protect the equipment.

The explosion proof valve is a safety valve which can eliminate the shock wave and can block

the water hammer shock wave, and the product is composed of a plurality of groups of safety

valves, and the function of the safety valve can not be achieved.

The exit of the product is installed in the water supply pipe and the head of civil air defense to

transport medium, to block wave and wave combination, to prevent internal shock wave into the

system engineering facilities, so as to eliminate the destructive shock wave, to protect the system

facilities normal operation and safety protection purpose.

Under normal conditions the valve is normally open, medium normal flow, when the shock wave into

the valve, the main valve valve to overcome the impact of spring strength, rapid closure of the shock

wave in the outer end, just enter the shock wave in the wave valve under the action of the wave

chamber, resolve the destructive force of shock wave, through the barrier and resolve to achieve the significance of protection.

Pressure Relief Valve, Body Material: Carbon Steel,  Trim material:  stainless steel

The valve instantly opens when the pressure in the pipeline exceeds the preset safe level, thus relieving excessive pressure from the pipeline. When the pressure returns to normal, the valve closes slowly, at an adjustable speed. The valves also can be used to sustain upstream pressure to a preset pressure value.
