Description

Pneumatic two-way hard seal eccentric half ball valve

The Pneumatic Two‑Way Hard‑Seal Eccentric Half Ball Valve delivers precision flow control by combining an eccentric half‑ball mechanism with hard metal seals to ensure a bubble-tight shut-off under high pressure and abrasive media. As a pneumatic eccentric half ball valve hard seal design, it uses a double-offset structure where the half-ball drifts away from the seat during rotation, creating minimal friction and avoiding wear until the final seal engagement. This valve is ideal for controlling steam, gas, slurries, and particulate-laden flows, preventing sticking or jamming thanks to its hard seal stainless steel or Stellite seat—a hallmark of metal-seated eccentric half ball valve engineering wsd-valve.com+11jinbinvalve.com+11hiseavalve.com+11.

Equipped with a pneumatic actuator, this valve acts as a two-way valve offering remote operation, fast actuation, and precise flow isolation. Its straight-through flow design minimizes pressure drop while ensuring full direction control. The eccentric structure also provides a self-cleaning effect at seal engagement, cutting abrasive scale or particles to maintain sealing performance .

Built to stringent standards—ISO 5752 dimensions, ISO 5208 pressure testing, and flange compliance (EN1092‑2 PN10/16/25)—this valve ensures compatibility and secure installation in critical piping systems jinbinvalve.com. Its body is made from carbon steel (WCB) or stainless steel (CF8/CF8M), with stainless stems and hard alloy seats featuring seat compensation to prolong life. Packing is reinforced for seal reliability

This hard-seal design is ideal for industries like metallurgy, power generation (e.g., pulverized coal injection systems), chemical processing, and gas transport, where abrasive two-phase flows demand robust valves.. Its pneumatic actuation supports integration with process controls, enabling responsive, automated operations.

Safety features include low torque operation, anti-wear seat materials, and options for fail-safe actuation. Maintenance is simplified since the valve seat is serviceable without replacing the entire valve  The two-way design also removes the need for an additional check valve, saving space and potential leak points.

Choose this Pneumatic Two‑Way Hard‑Seal Eccentric Half Ball Valve for high-integrity, low-maintenance flow and isolation control—it’s the preferred option when performance, durability, and automation matter most.
