- Good pressure / flow characteristics, see graphs.
- Valve body in zinc plated carbon steel.
- Piston in carbon steel.
- Internal spring in silicon steel - stabilized.
- Cracking points 5 psi and 65 psi are standard, other values on request.
- As a pressure sequence valve by changing the internal spring to an appropriate 'cracking point' value.
- For flow restrictor check valves a central bleed hole can be provided, sized to customer requirements.
