The Seetru Product Range

With a wide range of bore sizes, material options (bronze, brass, or stainless steel), and connection types (threaded, flanged, or weld end), Seetru’s safety relief valves accommodate a wide spectrum of applications and pressure requirements, covering bores from 10mm to 30mm and temperatures up to 250°C. 

Change-over valves (sometimes referred to as selector valves or three-way valves) enable the switching of flow from one safety valve to another. Typically used where plant shutdown is impossible or undesirable for process, engineering, or commercial reasons.  With these valves, it is possible to switch over between parallel safety valves without interrupting operation, so that maintenance work can be carried out on each safety valve in turn. 

The Seetru P3W Pressure & Temperature relief valve provides protection against both excess temperature as well as over pressurisation.  The valve will automatically discharge hot water at a predetermined set pressure and/or temperature.  Each of the lift mechanisms will work independently of each other. The valve is designed to be used in hot water boiler applications.

In the critical world of fluid control, Seetru’s auxiliary valves silently ensure your system runs smoothly and safely. From preventing backflow with check valves to guaranteeing precise pressure with minimum pressure valves, each compact valve plays a vital role. Air start valves deliver rapid pressure bursts while isolating valves segment flow for maintenance.

Accurate liquid level monitoring is crucial, whether you’re navigating the high seas or managing critical industrial processes.

Seetru offers a comprehensive range of liquid-level gauges and indicators designed for precise, reliable measurement in diverse applications.

Seetru circular window sight glasses are compact low-cost assemblies that provide reliable level indication and positive indication when liquid is present. These screw-in plugs are fitted with high-quality glass. They are suitable for a wide variety of liquids including water, oils, and lubricants. They operate at temperatures up to 180°C and pressures up to 24 bar
