Frequently asked questions
What cracking pressures are available for your check valves?
The standard cracking (opening) pressure is 1 bar. We offer 0.2, 0.5, 1, 2, 3, 4, 5, and 6 bar options. Please specify your required cracking pressure when ordering. The actual cracking pressure has a ±20% tolerance per DIN standards.
Can the check valve be installed in any orientation?
Yes. Our spring-loaded check valves can be mounted vertically, horizontally, or at any angle. The arrow on the body indicates the permitted flow direction. Ensure the arrow points in the direction of intended flow during installation.
