Product Description:
Pneumatic stop valve adopts a double-acting cylinder, and the valve is controlled by the upper cavity air inlet or the lower cavity air inlet for long-distance control. Cylinder use medium: compressed air, nitrogen. Pneumatic flange globe valve is simple in structure, easy to manufacture and maintain; 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.
Product Features:
1. Exquisite selection of materials, in line with domestic and foreign relevant standards, reasonable structure and beautiful appearance.
2. The sealing surface of the valve flap and the valve seat is made of iron-based alloy surfacing or Stellite cobalt-based hard alloy surfacing, which has good wear resistance, high temperature resistance, corrosion resistance, abrasion resistance and long service life.
3. The valve stem is quenched and tempered and the surface is nitrided to have good corrosion resistance and scratch resistance.
4. Various piping flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements.
5. The valve body has a complete variety of materials, and the packing and gasket can be reasonably selected according to the actual working conditions or user requirements, which can be applicable to various pressure, temperature and medium working conditions.
6. Inverted seal is made of screw-connected sealing seat or body surfacing austenitic stainless steel. The seal is reliable. Replacing the packing can be performed without stopping the machine, which is convenient and quick, and does not affect the system operation.
