MSI Relief Valves

MSI Relief Valves

The MSI Pressure Relief Valve is designed to provide over-pressure protection for high pressure equipment up to 15,000 psi (i.e. pumps, treating lines, pressure vessels, etc.).  The pressure relieving design incorporates a spring loaded ball that seals against a seat.  When the relieving pressure is reached, the spring force is over come and the ball separates from the seat.  This ball movement allows fluid to exit the relief valve, therefore keeping the pressure from increasing.  Fluid exiting the relief valve consequently warns the user that the preset relieving pressure has been reached.  The relief valve will reseat once the line pressure has dropped to a value below the relieving pressure.
