XAB KLV check valve

The KLV series check valves are available for connection to pipework or hoses in sizes 50, 60 and 63 mm, both with and without microswitches.

The design ensures that the flap valves do not leak, thanks to a robust O-ring and a conical cover. This combination means that the valve becomes tighter the greater the negative pressure to which it is subjected. The valves feature a robust and easily replaceable microswitch, as well as a strong spring that keeps the cover closed.
