Metal hard seal air actuated butterfly valve
The Metal hard seal pneumatic butterfly valves from our company serve various industrial needs through their use in potable water systems and wastewater management and seawater treatment and HVAC and steam applications. The stainless steel bodies of these valves support discs made from stainless steel materials including CF3M and CF3 and CF8M and double stainless steel and 2507.
The valves support EN 1092 PN 6/PN10/PN16 and ASME Class 150 and AS 4087 PN 10/ PN 16 and JIS 5K/10K flange standards. The valve stem consists of stainless steel material while the seats use F316 / F316L / F304 / F304L / A105 + STL materials and operate between -40 °C and + 538 °C based on pressure and medium and material selection. The valve features a wafer or LUG or Flange body design with a bi-directional replaceable valve seat. The pneumatic actuator provides maximum output torque of 8000 Nm while supporting NAMUR accessories. The product range includes specialized coatings and materials which protect against corrosive substances in harsh environments.

Pneumatic Actuator
Our pneumatic actuator system delivers high performance through its output torque capabilities which span from 10Nm to 8000 Nm. The actuator provides exceptional flexibility through its three control options which include double acting and single acting normally closed and single acting normally open configurations.
The actuator system includes multiple pneumatic accessories including solenoid valves and limit switch boxes and filters and E/P positioners and hand wheels which enhance operational performance and user convenience.
FAQs
What is a triple eccentric butterfly valve？
The triple eccentric butterfly valve operates as an industrial control device which manages fluid and gas and steam flow in oil and gas facilities and power plants and chemical processing and water treatment operations. The valve operates effectively in demanding applications because it delivers high performance and durable operation and dependable operation.
The triple eccentric butterfly valve operates differently from standard butterfly valves because it uses an asymmetrical cone-shaped disc that moves off-center from the seat during operation. The special design of this valve achieves complete sealing at all operating pressure levels and enables precise flow regulation.
What is a hard seal butterfly valve？
The hard seal butterfly valve functions as an industrial valve which controls fluid flow in various applications. The valve contains a disc-shaped closure element called a “butterfly” which spins on a central axis to manage the valve’s open and closed positions.
The valve distinguishes itself through its distinctive sealing system which operates differently from soft-seal valves that use rubber or elastomeric materials. The hard seal butterfly valve achieves its airtight seal through direct contact between metal components instead of using rubber or elastomeric materials like soft-seal valves.
What are the applications of triple eccentric hard seal butterfly valve?
The oil and gas industry represents a primary use case for triple eccentric hard seal butterfly valves. The valves operate in pipelines to control the movement of crude oil and natural gas and refined products. The strong construction and resistant materials of these valves enable them to operate effectively in the demanding conditions which prevail in this industry.
