A: The VRT3-310 Unloader Valve features dual 3/8" female inlet fittings and a 3/8" female outlet fitting, making it compatible with a wide range of residential and commercial pressure washing systems that use standard 3/8" quick-connect fittings. Always verify your pump's port sizing before installation.

Q: What is the purpose of the bypass port on this brass unloader valve?

A: The bypass port fitting safely redirects excess water flow back to the inlet or a reservoir when the spray gun trigger is released. This protects your pump from excessive pressure buildup, extends pump life, and keeps the system operating efficiently during use.

Q: Can I adjust the pressure output on the VRT3-310 Unloader?

A: Yes. The VRT3-310 Unloader Valve is equipped with a convenient adjustment knob that allows you to manually fine-tune the operating pressure up to 4,500 PSI. This lets you customize the output to match different cleaning surfaces and tasks without requiring additional tools.

Q: Why is brass used for this unloader valve?

A: Brass is the industry-preferred material for high-pressure water fittings and pump components. It offers excellent corrosion resistance, handles high operating pressures with ease, and provides long-term durability even under demanding, continuous-use conditions.
