PFA Suck Back Valve

The high-pressure suction switch valve adopts an upward movement closing structure, so that the broken material is instantly sucked back at the same time as the stop, reducing the residual flow on the remaining needle, so that the medium does not produce leakage, drawing and other phenomena. Suitable for high-viscosity liquid substances, with a suction function; with a piston stroke adjustment structure and a suction structure to prevent liquid leakage; auxiliary air inlet air-assisted closure.
