Product Description
The Graco 236770 is a low-pressure mini back pressure regulator designed to maintain system pressure independently of flow demand. This manual regulator features a maximum regulated pressure of 180 psi and accommodates flow rates up to 4.3 GPM (16.28 L/min), making it suitable for small circulation systems where compact design and lightweight construction are essential.
- Maximum working pressure: 300 psi (21 bar, 2100 kPa)
- Inlet and outlet: 3/8 inch NPSM threads
- Wetted materials: Stainless steel, tungsten carbide with nickel binder, acetal, and PTFE
- Compatible with catalyst and waterborne materials
- Maximum fluid viscosity: 1000 cP
- 1/4 inch NPT gauge port for pressure monitoring
- PTFE and elastomer hybrid diaphragm for durability and responsiveness
This regulator uses closed-loop control to allow operators to trigger guns, valves, and other flow controls without changing system pressure. Stainless steel construction and tungsten carbide components ensure long service life with minimal wear. For automated control applications, an air-operated model is available with conversion kit 237448.
