Description
1/8" & 1/4" Brass Water Pressure Reducing Valve – Shako UBR200
The Shako UBR200 is a compact, adjustable brass water pressure reducing valve designed to regulate downstream water pressure in miniature fluid control systems. Available with 1/8" and 1/4" BSP threaded connections, this piston-operated pressure regulator provides convenient pressure adjustment from 0.5 to 7 Bar, making it ideal for water treatment equipment, laboratory systems, OEM machinery and small industrial water installations.
Featuring a robust brass body, EPDM sealing and a precision piston regulating mechanism, the UBR200 helps maintain a controlled outlet pressure where the incoming water supply pressure may be higher than required.
Its compact construction, easy-to-adjust control knob and optional pressure gauge make it particularly suitable for installations with limited space.
Pressure Regulation & Operation
The UBR200 uses a spring-loaded piston mechanism to reduce inlet water pressure to a selected downstream setting.
Turning the adjustment knob changes the regulator setting, allowing the outlet pressure to be adjusted to suit the application.
The regulator is a non-relieving design and does not automatically discharge excess downstream pressure when the outlet pressure rises above the selected setting.
