Pisco JKC4-01B1p7IN 4mm x OUT R1/8" Straight 1.7mm Orifice Meter-In Check Valve

The Pisco check valve regulates unidirectional airflow by using a 1.7 mm orifice that opens in one direction and obstructs flow in the opposite. It features a meter-in configuration, allowing controlled flow from the push-in fitting port to the male threaded port. The valve's cracking pressure is 0.5 bar. Its 4 mm push-in fitting simplifies tubing connections, while the R 1/8 inch male threaded port on the opposite end ensures versatility. The valve operates within a pressure range of 1 to 9 bar and a temperature range of 0 to 60°C. Its NBR seals enhance its suitability for applications in the United Kingdom.
