Spring check valve with a spool mechanism (stem, upper, lower plates) of nylon (glass-filled polyamide), which is characterized by mechanical, thermal, chemical resistance. Spring material – stainless steel. The body of the product is manufactured by the method of volumetric hot stamping from high-quality brass with electroplating (nickel plating). Connection thread is internal. The direction of flow is indicated by an arrow on the body. This check valve is mounted in any position, there are no rubbing surfaces.
