LYV® Pneumatic Angle Seat Valve Introduction
Buy Hot Pneumatic Angle Seat Valve made in China. LYV® is a Pneumatic Angle Seat Valve manufacturer and supplier in China. This valve adopts double acting cylinder, using the upper chamber intake or lower chamber intake to remotely control the valve, easy to operate, flexible. Cylinder using medium: compressed air, nitrogen. Simple structure, convenient manufacture and maintenance; Small working trip, short opening and closing time; The closing body (disc) and the sealing surface of the seat adopt conical sealing, small closing force, erosion resistance, reliable sealing. The seat can be a replacement seat, can be any combination with the sealing material of the closing part, in order to meet the requirements of working conditions, prolong the service life
LYV® Pneumatic Angle globe valve Feature And Application
1, material selection, in line with domestic and foreign relevant standards, reasonable structure, beautiful shape.
2. The sealing surface of valve disc and valve seat is made of iron base alloy surfacing or Stellite cobalt-based hard alloy surfacing. It has good wear resistance, high temperature resistance, corrosion resistance, abrasion resistance and long service life.
4, the valve stem after conditioning and surface nitriding treatment, has good corrosion resistance and abrasion resistance.
5. Various pipe flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements.
6, the valve body material variety is complete, packing, gasket can be reasonably selected according to the actual conditions or user requirements, can be applied to a variety of pressure, temperature and medium conditions.
7, the reverse seal is made of threaded sealing seat or body surfacing austenitic stainless steel, reliable sealing, replacement packing can be carried out without stopping the machine, convenient and fast, does not affect the operation of the system.
Working principle Most valves using compressed air as power source are controlled remotely. Manual or automatic action instructions are triggered by the main control room to make the inlet and exhaust solenoid valves operate to supply and discharge compressed air to the actuator. The compressed air acts on the piston or diaphragm, the friction force of the valve action and the spring force of the stem, which depresses (for the loss of air open valve) or lifts (for the loss of air close valve) the stem, driving the spool up and down to open or close the valve.
