P630R High Flow Gas Relief Valve • Stainless Steel Internals are Standard • Steel Units comply with NACE MR0175 • Durable Powder Coated Exterior • High Flow Capacities
Applications
The BelGAS P630R is a spring loaded, adjustable relief valve designed for relief pressure settings from 3 PSIG to 250 PSIG (0.21 to 17.3 BAR). The heavy duty construction, made possible by the addition of stainless steel internal components and a powder-coated epoxy exterior finish, makes it ideally suited for the oil and gas industries. All P630 steel units meet NACE MR0175 material requirements for corrosive (sour gas) environments.
