Product description
100 series of pilot control valve sleeve (series100pilotcagecontrol
Valve) is a pressure balance valve, valve parts by the pilot valve sleeve guide, it mainly uses the fluid pressure to achieve quick action valve, the operating force, seal the single-seat sealing, flow characteristic curve of high precision, regulating valve dynamic stability, low noise, air defense, suitable for high pressure difference liquid control temperature. It was streamlined s channel, the pressure drop, flow is large, wide adjustable range, the flow characteristics of high precision, is my company to introduce advanced foreign technology and then after a super high performance of new products in twenty-first Century after optimization of our R & D personnel conforming to iec534-2-1976 standards.
Control valve with 812 type spring pneumatic diaphragm actuator, simple and firm structure, large output force, long service life.
