SEETRU Celebrating Over 60 Years Of Quality, Innovation & Service The Company Seetru Limited was founded in 1949 with the aim of producing the nest liquid level gauges so customers could see the true level even under the most severe conditions. This philosophy of making the nest through innovation continued with the introduction of the Seetru range of pressure relief devices, circa 1950; the Seetru Tutchtite® sealing system revolutionized the safety valve market with valves that do not leak even after repeated popping and for high pressures. Today, Seetru have an extensive range of pressure relief...

Auxiliary Valves 6 The Seetru 'MPCV' & 'COV' Range The Seetru range of auxiliary valves includes Minimum Pressure Check Valves and Changeover valves. Minimum Pressure Check Valves are control valves typically suitable for application on compressors. Changeover valves allow two safety valves to be mounted side by side; with one in service and one isolated. This means regular maintenance can be carried out on one valve at a time without interruption of service or the vessel being un-protected. MPCV 419 (Minimum Pressure Check Valve) From Connections Pressure range To BSP & NPT R1 1/4” x G1 1/4”...

The Seetru Air Start Valve (GS56) 6 Auxiliary Valves The Seetru GS56 is a high quality control valve designed to handle a two-stage operation for air starting of engines. Air starting is typically used for diesel engines. The GS56 is bolted onto the air receiver vessel and integrates all the necessary functions and connections into one highly effective unit. It controls charging of the pressure vessel with the air for starting and it controls the flow of the air to the engine to start the engine. Incoming air and outgoing air are kept separate to comply with regulations. The unit configuration...
