Bonney Forge’s premium gate valves deliver exceptional performance for demanding industrial applications where reliable on-off service and minimal flow restriction are essential. Available in two distinct bonnet designs to meet diverse operational requirements:

• Bolted Bonnet Design: Features a male-female joint with F316L/graphite spiral wound gasket for superior sealing integrity. Ring joint gaskets available upon request for specialized applications.
• Welded Bonnet Design: Incorporates a threaded and seal welded joint, with optional full penetration strength welded joints for maximum durability in extreme conditions.

These valves excel in applications requiring straight-line flow with minimal pressure drop. When open, the wedge-shaped closure member fully retracts, creating an unobstructed flow path that maximizes efficiency and minimizes turbulence.

Technical Specifications

• Full die-forged construction for all pressure-containing components
• Integral flanged connections with body forgings
