Custom Gear Operated Flange Butterfly Valve Manufacturer & Suppliers

When reliable, precise manual control is required for mainline isolation, a robust gear operator is the trusted solution. Engineered for applications where consistent sealing and smooth operation are critical, this valve combines durable construction with user-friendly mechanical control.

Manufactured with a fully lined body and precision-machined disc, our flange-type Butterfly Valves are designed for long-term, leak-tight service. The enclosed weatherproof gearbox provides clear visual indication (open/close) and significantly reduces operating torque, allowing for safe and efficient control of larger diameter lines—even under full differential pressure.

Built for Performance & Durability:
• Design: Wafer or lug flange pattern, PN10/16 rating
• Body & Disc: Ductile iron with epoxy coating (standard); 316 stainless steel or other alloys available
• Liner/Shaft Seal: Resilient EPDM seat & seals (standard); multiple elastomer and PTFE options
• Gear Operator: Enclosed, weatherproof housing with position indicator and adjustable stop lugs
• Size Range: DN150 to DN1200 from standard production
• Optional Features: Locking device, extension shaft for buried service, secondary sealing provisions

Every valve is assembled, cycled, and hydrostatically tested in our factory. We control the entire process—from component machining to gearbox integration—ensuring a fully validated, ready-to-install unit arrives on your site.

A dependable, mechanical workhorse for water, HVAC, and industrial services. Request detailed specifications or a quote for your next project.
