Pisco JKL4-01B1p4IN 4mm x OUT R1/8" Angled 1.4mm Orifice Meter-In Check Valve

This one-directional check valve regulates fixed air flow control with its meter-in elbow orifice design. Its 1.4 mm orifice restricts flow in one direction and enables free flow in the opposite direction, with a cracking pressure of 0.5 bar. Metering occurs from the push-in fitting to the male threaded port. The valve features a 4 mm push-in fitting for effortless tubing connections, secured by stainless steel claws. The operating pressure ranges from 1 to 9 bar (14.5 to 130.5 psi). Its NBR seals allow operation within a temperature range of 0 to 60°C (32 to 140°F), excluding freezing conditions. This product is available for purchase in the United Kingdom.
