Seetru Limited, founded in 1949, is a manufacturer of high-quality liquid level gauges and pressure relief devices. Known for its innovative Tutchtite® sealing system, the company ensures leak-free performance under high pressure. Seetru's products are globally recognized and hold numerous international approvals.
Seetru offers safety relief and ancillary valves for applications such as compressed air, industrial gases, refrigerants, steam, and liquids. Their products comply with standards like BS 6759, AD-Merkblatt A2, ISO 4126, and ASME Section VIII, and meet the European Pressure Equipment Directive 97/23/EC with approvals like CE, UV stamp, GOST, RTN, and CRN.
Specialized valves are available for the compressed air industry and medium-sized industrial diesel engines, including minimum pressure and air starting valves.
Seetru's liquid level gauges include sight gauges and magnetic float by-pass gauges, with options for electronic remote reading and computer interfaces. Notable models include Quickmount, Seemag, CPI, and Seeflex.
Seetru's design and development department offers bespoke design and manufacturing services, supported by TÜV-approved testing facilities.
The GA and GP range of safety valves are compact and efficient, featuring Tutchtite® seal technology. Suitable for air/gas compressors, chemical equipment, and medical gases, these valves are made from materials like bronze, brass, and stainless steel, compliant with various international standards.
Models GA 81806, 81706, 81106 have a 6 mm nominal bore, pressure range from 2.80 to 36.00 bar g, temperature range -30°C to 200°C, and flow area of 28.27 mm². Models GA 81808, 81708, 81108 have an 8 mm nominal bore, pressure range from 0.55 to 21.00 bar g, temperature range -15°C to 200°C, and flow area of 50.27 mm². Models GA 81810, 81710, 81110 have a 10 mm nominal bore, pressure range from 0.48 to 46.00 bar g, temperature range -15°C to 200°C, and flow area of 78.54 mm².
Pressure range from 0.48 bar g. (6.96 psi g.) to 46.00 bar g. (667.00 psi g.). Temperature range from -15 °C to 200 °C, depending on seal material.
Flow area is 78.54 mm² with a 10.00 mm inlet bore diameter. Inlet connections available in 1/2" to 3/4" BSP, BSPT, NPT.
Body and plunger made of Brass CW614N, seal made of Viton, spring made of stainless steel (1.4310 or 1.4401), and adjuster and lifting cap also made of Brass CW614N. Nameplate is aluminum alloy, and wire & seal are stainless steel & lead.
Approved by TÜV Germany, BS EN ISO 4126-1, ASME Section VIII Division 1, and PED 97/23/EC. Relieving pressure is set pressure +10%, and reseating pressure is set pressure -10%.
Includes various models such as GA 81810, GA 81813, GA 81815, and GA 73008, each with specific pressure, temperature ranges, and flow areas. Each model is designed for compressed air and gases and is PED, TÜV, and ASME approved.
The valves operate stably at flows down to 50% of their rated capacity. Relieving pressure is set at +10% of the set pressure, while reseating pressure is -10% of the set pressure, with a minimum of 0.3 bar g.
Graphs illustrate the discharge capacities of the valves in kg/hour, scfm, and litres/sec against pressure in bar g., providing a visual representation of performance across different models.

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...
