Gresswell比例提升安全阀Proportional Lift Safety Relief Valves G55/G90/G36

Gresswell's Proportional Lift Safety Relief Valves provide an extremely cost effective solution for applications requiring a steady flow and are used extensively for by-pass and regulation to ensure pressure balance is maintained within a system. They are particularly suited to liquid management. The G55 and G90 valves are available in Bronze while the G36 model is produced in Stainless Steel. A range of fitment elements accomodates pressure variations up to 21 bar.g with screwed or flanged connection sizes from 15 to 80mm.

Where greater lift and higher flows are required for the management of 'compressible' media, the High Lift Safety Relief Valve provides the perfect solution by the inclusion of an adjustable 'Blow-down Ring'. Ideal for boiler room applications, these valves 'pop' to give high discharge rates and protect plant from over pressure. Cast in Bronze, they are available for pressures up to 21 bar.g, and connections up to 50mm in size which can be screwed or flanged.

Winners of the SPUR award to industry, these ranges represent the pinnacle of 'value for money' by combining the benefits of both Proportional Lift and High Lift valves. Their excellent shut off characteristics and very high flow capability means that more compact valves can be used with the benefit of initial cost savings and smaller associated fittings. in sizes up to 50mm, with a variety of seat assemblies and materials (Bronze and Stainless Steel) they suit all applications from screwed for general purpose to flanged for process duties and are available for pressures up to 12.5 bar.g.
