The Bi-directional Flow Swivel Ball Valve, also known as the "Hard-to-Hard Swing Ball Valve," features its primary material and working principle.

Hard-to-hard bidirectional flow ball valve, main material

Body: Carbon steel (except as noted in the goods requirement list)

b) Valve Plate: Stainless Steel

c) Valve Rod: Stainless Steel

d) Sealing Surface: Hard alloy of cobalt-based surfacing.

Technical Requirements

Resistant to wear and tear from sand and mud.

b) Valves offer flexible opening and closing, unaffected by the pressure levels of the medium.

c) The valve seat and valve plate have no opening and closing friction, featuring an increasingly tight sealing as it is closed.

d) The valve plate gasket features a sealing compensation function.

Hard-Hitting Bi-Directional Flow Swivel Ball Valve Technical Specifications

The bi-directional swirling ball valve, which is a eccentric structure worm gear driven flanged ball valve, contacts media such as raw water from reservoirs, turbine oil, or insulating oil. It features a metal-to-metal sealing design and is powered by a worm gear and worm drive. The ball valve allows bi-directional flow while maintaining the required sealing performance in both directions up to the nominal pressure.

Hard-to-Hard Bidirectional Flow Swivel Valve: Main Types and Working Principle

1. Main Types: The primary types of our valves include worm gear, electric, pneumatic, and hydraulic. Among them, pneumatic and hydraulic valves are suitable for applications with pressure gas and pressure liquid sources.

2. Working Principle: The key function of a bidirectional flow valve is to seal effectively under both forward and reverse pressure conditions, even when reverse pressure exceeds forward pressure. When forward pressure is applied, the medium pressure pushes the valve plate forward, causing the valve stem to deform. The sealing surface of the valve plate is in close contact with the sealing surface of the valve seat, transferring pressure to push the valve seat against the body step for a good seal. When reverse pressure is applied, the medium pressure pushes the valve plate backward, causing the valve stem to deform again. Simultaneously, the medium pressure also pushes the valve seat backward, with the sealing surface of the valve seat in close contact with the sealing surface of the valve plate to transfer pressure and ensure a good seal.
