Safety Valves
GRUPA WOLFF delivers a broad assortment of safety valves intended for liquids, gases and vapours. Moreover, we install pipework systems equipped with necessary fittings. Our offer includes a broad assortment of pilot controlled and weight-driven spring-weighted valves.
Safety valves should be applied wherever the pressure in the system (e.g. in a tank, device or process plant) can exceed the critical value. Such a situation occurs wherever media in the form of gases, vapours or liquids are subject to compression or heating or are transported as a result of a pressure difference.
We will answer questions about: offer, technical specification, delivery, assembly.
1. PILOT CONTROLLED SAFETY VALVES
Pilot controlled safety valves are characterised by a high precision of action and efficiency. Such type solutions are generally applied for pumps, pipework systems, tanks, heaters, gas and oil separators, as well as for other process equipment. Due to patented design solutions, the valve can operate at pressure ranging at 95 – 98% of the opening pressure and at the same time, it is characterised by a lack of the opening delay.
The pilot controlled safety valves offered are technically advanced, proven solutions manufactured as per ISO9001: 2008. Due to our policy of constant development, the products achieve the optimum efficiency level and a high reliability.
This category products have PED and ATEX certificates as required by the EU law.

2. SPRING-WEIGHTED SAFETY VALVES
Standard spring-weighted safety valves – this type valve is characterised by a complete opening and can be applied for both medium and high capacities. This solution is successfully applied for pumps, blowers, pipework systems, tanks, heaters, gas and oil separators, as well as for other process equipment.
Spring-weighted safety valves for thermal expansion of fluids – this type of valves has been designed for protection of tanks and long pipework systems where in view of the thermal expansion of the medium, a high precision of action and low capacities are required. The valve can be applied for gases and liquids.
