Description
This is a meter-in straight orifice check valve for one-directional fixed air flow control. It has a 1.4 mm orifice that obstructs the flow in one direction and opens in the opposite direction providing the free flow. The check valve''s cracking pressure is at 0.5 bar. The meter-out configuration implies that the flow is affected (controlled) going from the male threaded port to the push-in fitting port. It is the other way around for the meter-in configuration.
It has a 8 mm push-in fitting on one side and an R 1/4 inch male threaded port on the other side. The push-in fitting provides an easy connection with the tubing. Push the tube in and the fitting will fix it with stainless steel claws. The flow is metered going from the push-in fitting port to the male threaded port.
The operating pressure ranges from 1 to 9 bar (14.5 to 130.5 psi). It has NBR seals that make it suitable for applications within a temperature range from 0 to 60°C (32 to 140 °F) (no freezing).
Pros:
- Small installation place
- Lower cost than a flow control valve
- Equipped with easy to connect push-in fittings
Cons:
- Non-adjustable orifice size
- Not suitable for vacuum applications
JKC series
The JKC – series includes straight orifice check valves designed for one-directional air flow control. The threaded fitting side male threaded sizes range from R1/8 to R1/4 inch with 18 different possible orifice fitting sizes ranging from 0.3 to 2.0 mm. The push-in fitting sizes range from 4 to 8 mm. These valves are suitable for a maximum operating pressure of 9 bar. These orifice fittings are sealed with NBR O-rings that make them suitable for temperatures ranging from 0 to 60°C.
