Description

1. Features:

This series of products is suitable for flammable, explosive or non-powered working occasions, especially in the fully air-controlled pneumatic system, which shows its unique reliability.

This series of valves is a monostable reversing element, and there are two structural forms, namely "normally open" and "normally closed".

When the valve receives the signal, the spool shifts; after the air signal is eliminated, the spool automatically resets and the valve returns to its original working state. This series of valves has the characteristics of less sliding mating surface, low air purification requirements, and strong anti-dust ability.

Valves of this series of valve diameters below 25mm are plate connection, and valves above 32mm are flange connection.

 FXS, FXSa series muffler
FXS, FXSa series muffler
FXS and FXSa series mufflers are absorption mufflers that use copper bead sintered cups as sound-absorbing materials, which have a good noise reduction effect on the mid-to-high frequency range of aerodynamic noise.
 23JQ-L15 Pneumatic Control Valve
23JQ-L15 Pneumatic Control Valve
The valve is a cut-off structure to control the on-off, conversion and distribution of air flow.
 QTY series air pressure reducing valve
QTY series air pressure reducing valve
The air pressure reducing valve is used under the condition that a certain air pressure needs to be maintained in the general pneumatic control system and general pneumatic pipeline.
 Internal pilot operated pressure reducing valve PJXN-L40-L50
Internal pilot operated pressure reducing valve PJXN-L40-L50
The PJXN pressure reducing valve mainly achieves the purpose of controlling the pressure of the main valve by adjusting the gas pressure of the pilot valve. It belongs to the internal pilot pressure reducing valve. A small pressure reducing valve controls a large pressure reducing valve. Compared with the pressure valve, the adjustment is labor-saving, the output pressure fluctuation is small, and it is widely used in the control system of large flow and high pressure.
