J641H Pneumatic Flanged Stop Valve Main Application:

This valve features a double-acting cylinder for remote control of the valve through either the upper or lower cavity, offering easy and flexible operation. The cylinder operates with compressed air or nitrogen. The structure is simple, and both manufacturing and maintenance are convenient; it has a short working stroke and quick opening/closing times. The sealing surface of the closure body (valve disc) and valve seat employs a conical seal, which provides minimal closing force, resistance to erosion, and reliable sealing. The valve seat can be a replaceable type, allowing for various combinations with the sealing surface materials of the closure pieces to meet process requirements and extend service life.

J641H Pneumatic Flanged Check Valve Structural Features:

Select materials meticulously, compliant with both domestic and international standards, with a reasonable structure and aesthetically pleasing design.

2. The valve disc and seat sealing surfaces are made by iron-based alloy surfacing or Stellite cobalt-based hard alloy surfacing, offering excellent wear resistance, high-temperature resistance, corrosion resistance, and abrasion resistance, with a long service life.

3. The valve rod has been heat treated and surface nitrided, offering excellent corrosion and abrasion resistance.

4. Various pipe flange standards and sealing surface types are available to meet diverse engineering requirements and customer needs.

5. A wide variety of valve body materials are available. Seals and gaskets can be reasonably selected according to actual operating conditions or customer requirements, and are suitable for various pressure, temperature, and medium conditions.

6. The inverted seal is made of a threaded connection seal seat or a body surfacing with Austenitic stainless steel, ensuring reliable sealing. The filling material can be replaced without shutting down the machine, offering convenience and speed, and without affecting system operation.
