GVF Series

Product catalog summary

Overview: The document describes the GVF Series air-actuated shut-off valve group designed for high-pressure water systems. It highlights the valve's components, options, general features, technical data, and available sizes.

Components and Accessories: The valve can be equipped with an actuator control unit, flanges kit, and base frame. Options include a stainless steel body and ANSI flange drilling.

General Features: The shut-off valve group is designed to prevent accidental emptying of accumulators. Key features include:

Shut-off valve closure ensured by internal constant pressure.
Valve opens only when pump pressure balances accumulator pressure.
Flow is allowed only from pumps to accumulator at low accumulator levels.
Intrinsically normally closed (NC) function if no piloting air or electricity is present.

Technical Specifications:

Fluid: Water and HFA
Working Pressure: 350 bar (35 MPa)
Ambient Temperature: +2°C to +60°C
Pneumatic Feeding: Lubricated compressed air 5 to 7 bar (0.5 to 0.7 MPa)
Materials: Body in carbon steel, internal parts in stainless steel and bronze

Design and Safety Features: The valve group offers high reliability for heavy and continuous duties, with open/close switching from 0.1 seconds. Safety is enhanced by the sequential closure of two valves. It includes an electric actuator and/or manual hand-wheel, in-line connection, metal-to-metal seal, proximity switches, compact design, no welds, and easy maintenance.

Valve Sizes: Available sizes range from DN 100 (4 inches) to DN 200 (8 inches).
