ST261 Unloader Valve
R+M Suttner ST261 pressure-actuated unloader valve, rated to 250 bar, 30 litres per minute and 80°C, with 3/8" BSP female inlet and outlet.
When the wash gun trigger is released, pressure builds against the valve until it overcomes the spring tension and the water is diverted to bypass. Adjusting the spring tension sets the working pressure.
To check thread sizes, see our BSP thread size chart.
