Relief Valves

TR ENGINEERING INCORPORATED SRV Series Relief Valves

TR direct-acting relief valves are vented to the atmosphere, and designed as safety valves. Poppets are heat-treated alloy steel or stainless steel. These valves are ideal for applications where a safety valve of small size is required. These small valves are ideal for lifting systems or any system using double-acting hydraulic cylinders with a large area ratio between the blind end and rod end. In case the return line is blocked these valves can prevent the pressure multiplier from damaging the cylinder. All stainless steel versions are available. Pressures are preset at the factory, and not intended for field adjustment.
