I. Overview of J641H pneumatic globe valve :

The valve adopts a double-acting cylinder, and the valve is controlled remotely by using the upper cavity air inlet or the lower cavity air inlet, and the operation is convenient and flexible. Cylinder use medium: compressed air, nitrogen. Simple structure, convenient manufacturing and maintenance; small working stroke, short opening and closing time; sealing body (valve) and valve seat sealing surface adopts tapered surface seal, small closing force, erosion resistance and reliable seal. The valve seat can be a replaceable valve seat, which can be arbitrarily combined with the material of the sealing surface of the closing member to meet the requirements of the working condition and extend the service life.

  Structural features of J641H pneumatic globe valve:


1. Exquisite selection of materials, meeting domestic and foreign relevant standards, reasonable structure and beautiful appearance.
2. The sealing surface of the valve disc and the valve seat is made of iron-based alloy surfacing or Stellite cobalt-based hard alloy surfacing, which is wear-resistant, high-temperature resistant, corrosion-resistant, good anti-scratch performance, and long service life. .
4. The valve stem undergoes quenching and tempering and surface nitriding treatment, and has good corrosion resistance and scratch resistance.
5. Various piping flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements.
6. The valve body has a complete range of materials. The packing and gasket can be reasonably selected according to the actual working conditions or user requirements, and can be applied to various pressure, temperature and medium working conditions.
7. The inverted seal is made of austenitic stainless steel with screw-connected sealing seat or body. The seal is reliable. The replacement of the packing can be performed without stopping, which is convenient and quick, and does not affect the system operation.
