How do I adjust the relief setting?
First, remove the chrome hex plug with a 7/8”combination wrench, etc and set aside. This gives you access to the
relief set screw (5/16” hex). Turning the set screw clockwise will increase the pressure.
• RL models: 1 turn is ~500psi[34.47bar]
• RLC models: 1 turn is ~ 800psi[55.16bar]
Can I paint my valve?
– Painting valves is okay as long as the all ports are properly plugged.
Pipe thread sealant – Warranty is void when Teflon tape is used to seal pipe threads. This is because Teflon tape is a friction
reducing agent which allows customers to over-torque fittings. We recommend using a sealant that does not include friction
reducing agents i.e. Lead Plate.
