Valves & Valve Fittings

We offer a complete product range of Pilot Operated Relief Valves, Solenoid Control Pilot Operated Directional Valves, Low Noise Type Pilot Operated Relief Valves, Proportional Electro-hydraulic Overflow Valves and Modular Reducing Valves

Pilot Operated Relief Valves

we are offering pilot operated relief valves. pilot operated relief valve has a variety of structures. figure 6.9 is a typical three sections concentric structure pilot relief valve, which consists of two parts by a pilot valve (pilot valve) and the main valve (main valve). the valve principle shown in figure 6.10. a pilot valve cone, on the main valve orifice (fixed orifice) 5 and regulator spring 9 together constitute the partial pressure of the pilot stage half-bridge type pressure negative feedback control, accountable to the main valve on the chamber 6 is provided through after the pilot valve regulator main stage command pressure p2. the main spool is the master comparator circuit, acts on the end face of the main spool instruction force p2a2, a lower end surface of the main circuit as a load, the feedback force acts p1a1, which force the valve body can be driven to adjust the overflow port size, and finally achieve the purpose of the regulator inlet pressure p1 and regulated. 1- cone valve (pilot valve) (pilot valve); 2 - cone seat (poppet seat); 3- bonnet (valve cap); 4- valve (valve body); 5- orifice (orifice); 6 - main spool (main spool); 7- main seat (main valve seat); 8- main valve spring (main spring); 9- regulator (adjustment spring) (pilot valve) spring; 10- adjusting screw; 11 - adjust the handwheel.

Solenoid Control Pilot Operated Directional Valves

We are offering solenoid control pilot operated directional valves, the diaphragm, inlet, outlet, switch, valve, etc., characterized by: a pilot outlet for straight pipes form; stepper motor or reversible motor connected to a microcomputer-controlled transmission, which in turn is connected with ceramic sheets with the switch connecting shaft, by a switch on the ceramic ceramic piece, a connecting shaft composed of a ceramic plate and the upper and lower fan-shaped ceramic sheets have two holes, a substantial portion of the remainder. Using the utility model provides the pilot control valve, completely eliminating the clogging device, reliability and stability greatly enhanced. Precision ceramic sealing films to open or close the pilot hole, sealed tight, closed flexible. Control power is small, the power control can be maintained without a steady-state on or off without maintained.

Proportional Electro-hydraulic Overflow Valves

We are offering proportional electro-hydraulic overflow valves. Electro-hydraulic proportional valve proportional solenoid valve is a corresponding action according to the voltage signal input, so that the work of the valve spool displacement, valve port size is changed and as electro-hydraulic proportional valve electro-hydraulic proportional valve after completing the pressure proportional to the input voltage, the output of the flow element. Spool displacement can also be mechanical, hydraulic, or electrical forms of feedback. Due to the form of electro-hydraulic proportional valve has a wide variety, easy to use a variety of electro-hydraulic system consisting of electrical and computer-controlled, high control accuracy, installation flexibility and strong anti-pollution and many other advantages, applications increasingly widened. In recent years, research and development production proportional cartridge valves and proportional valves fully take into account the multiple use of the characteristics of mechanical engineering, with a pilot control, load sensing and pressure compensation function. It is important for the emergence of mobile hydraulic machinery to enhance the overall level of technology. In particular, demonstrated its good prospects in electrical control pilot operated, wireless remote control and wired remote control operation.
