Description

Dresser-Rand ¾" Gate Valve – CF8M, Class 150, Flanged RF, Manual, API 600

The Dresser-Rand DRZRNS2049R156 is a precision-engineered ¾" manual gate valve designed for industrial process control in corrosive and high-pressure environments. Manufactured from ASTM A351 Grade CF8M stainless steel, this valve features a rising stem design, bolted bonnet construction, and flanged raised face (RF) end connections conforming to ASME B16.5. With a pressure rating of ANSI Class 150 / PN20, it supports applications up to 285 psi (19.6 bar) at 100°F (38°C) and withstands temperatures ranging from -29°C to 425°C depending on packing and gasket materials. Compliant with API 600/API 602 design standards and tested per API 598, this valve is ideal for critical flow control where durability and corrosion resistance are required. The valve is unused and sealed in original packaging.
