The Cla-Val Model 55L (UL Listed FM approved) Pressure Relief

Valve is a direct-acting, spring loaded, diaphragm type relief valve. The

valve may be installed in any position and will open and close within

very close pressure limits.

The Model 55L is normally held closed by the force of the compression

spring above the diaphragm. When the controlling pressure applied

under the diaphragm exceeds the spring setting, the disc is lifted off its

seat, permitting flow through the control. When control pressure drops

below the spring setting, the spring forces the control back to its

normally closed position. The controlling pressure is applied to the

chamber beneath the diaphragm through an external tube on the 55L.

Pressure adjustment is simply a matter of turning the adjusting screw to

vary the spring load on the diaphragm. The 55L is available in three

pressure ranges; 0 to 75 psi, 20 to 175 psi, 100 to 300 psi. To prevent

tampering, the adjustment cap can be wire sealed by using the lock

wire holes provided in the cap and cover.

Note: Also Available in Seawater Service Material
