K23JK series
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.
