V-shaped sealing ring: The piston seal adopts a V-shaped sealing ring, which has the best sealing, wear resistance and stability. Piston structure: The flow rate of the air compressor pressure regulator is 30% higher than that of the traditional diaphragm type. Unique design: The valve body structure is equipped with an overflow port to quickly reduce the pressure. Fast response speed: The air compressor pressure valve has high switching accuracy and fast response speed. Easy to use: compact, lightweight and simple to install. Can be installed inverted, vertically or horizontally according to customer preference Switch pressure range: 0.5-0.8 MPA (5-8 BAR) (90-120 PSI) Max.Volt240-Amp.20-MaxBar12-PSI175 is printed on the switch box Size: 16*9.5*10.5CM Air compressor pressure switch: type 3 Switch: 4 holes, thread: G1/4, pressure: 5.5 bar-8 bar Pressure regulator: 4 holes, thread: G1/4 (3 holes) + 1/8" (connect pressure gauge) 0 Back gauge: 2pcs, 40mm, G1/8 and 50mm, G1/4, coated brass connector aluminum, 0-180 psi Brass valve: 2, thread: G1/4, with hose connector, weight: about 46 grams Connector: galvanized iron, thread: G1/4 Color: Black Material: ABS and metal Maximum voltage: 240V Maximum rated current: 20A Pressure switch control range: 90-120 PSI Pressure relief regulator pressure adjustment range: 30 - 120 PSI Inlet and outlet ports: 1/4" BSP Note: The data are all measured manually, please allow 1-3cm error due to differences in light and display, there may be some color differences, please refer to the actual item received.
