Safety Relief Valves and Liquid Level Gauges Ver.1

Seetru Limited Quality, Innovation & Service 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 valves and liquid level gauges...

The Seetru range of safety valves for steam applications are compact and highly efcient, designed with the exclusive Tutchtite® sealing technology offering repeatable bubble-tight sealing performance. Typical uses of these valves include autoclaves, pharmaceutical industry, vending machines, hot water boilers, steam boilers and plants as well as clean steam applications. Suitable for use up to 250 ˚C and minimum dryness factor of 0.97. Manufactured in accordance with a wide range of international standards and approvals such as TÜV (Germany) to AD Merkblatt A2, That's Safety! National Board UV...
