Powertech Relief Valves are designed to control pressure in a system, most often in fluid or compressed air systems.
Features & Operations :
- These forged PRV are suitable for pressure application and protects systems / plants of all kinds from over pressure.
- Relief set pressure can be incresed or decreased as per requirement by rotating the head cap & lock nut in clockwise or anti-clockwise direction given on the top of body.
- Install the valve between the pump outlet as close as possible, any shut-off device in the discharge line. the preferable mounting position is vertical with the adjusting cap at the top.
- When the inlet pressure overcomes the set spring pressure on the poppet, the poppet lifts off the valve seat, allowing flow to bypass anad thereby balance the sysytems pressure.
- If the valve has not been actuated for a period of time, it may initially crack above the set cracking pressure.
- Cracking pressure is only sensitive to inlet pressure, and is not affected by outlet pressure.
- Valve flow may be reduced by the restriction of pipe and tubing connected.
- Variety of End Connections : NPT/BSP/Tube End etc, Female x Female, Male x Male, Male x Female etc. are available on client requirement.
Specifications :
- Available in size from 1/4" to 1"
- Maximum Working Pressure : 413 Bar @ 20°C
- Cracking Pressure Range : 0.6 to 413 Bar
