GSV & GSHV Series Cylinder and Manifold Valves

Sherwood GSV & GSHV Series global industrial cylinder & manifold valves are used in cylinders containing inerts, oxidizers and flammables. Valves are available with various inlets and outlet specifications, with or without pressure relief devices, and standard brass or chrome plated exterior.

Key Features & Benefits

Heavy-duty forged brass body for durability and high pressure
Precisely machined internal components meet the most stringent international valve performance standards
Pressure Relief Device (PRD) is a unitized plug design that provides excellent flow characteristics, ensures proper assembly and tamper resistance
Metal-to-metal seal below bonnet threads prevents pressure in the threads at top of valve body
Direct-drive stem design with optimized O-ring (GSV) or double O-ring (GSHV) seal reduces friction and operates at exceptionally low torque levels
Inlet and outlet thread configurations are available for a broad spectrum of customer, country and code specifications
Tapped for dip tube as required
