DIAMOND ENGINEERING WORKS manufactures compact, economic, enclosed spring loaded Pressure Relief Valves for relieving excess pressure from Piping, Receivers, Laboratory Autoclaves, Sterilizers, Pilot Plants, Filters, Instrumentation circuits, Pumps and Hydraulic or Pneumatic systems. These valves are ideally suitable for safety precaution against over pressure. The set pressure range is from 10 psig to 2000 psig in sizes 1/4” x 1/4” and 1/2” x 1/2” with BSP / NPT screwed connections. This valve consists of maximum integral guide area in the housing, which gives perfect alignment to the disc movement. It is above the seating area providing unobstructed flow thru seat bore and high lift capacity. Positive reseating is achieved by resilient disc in the standard valve, which is suitable for Air, Gas, Vapour or Liquid duties up to 200°C while providing greater resistance to chemical attack. The design consists of minimum components for smooth function and longer life. Is angle type solid Housing has provision for panel mounting systems. This pressure relief valve is manufactured from materials AISI 316, AISI 304 and Alloys. Diamond Engineering Works also design & develop pressure relief valves as per customers applications.
