Description
Covering 8 mm to 100 mm, this is DRP’s G.M. Horizontal Check Valve No. 4, Screwed. Fitted to prevent flow reversing when a pump stops or a line depressurises. Orientation matters: a swing pattern needs the correct attitude to seat properly, so confirm the intended mounting before ordering. Gunmetal to IS 318 Grade LTB-2 holds up in continuous water service without the dezincification that shortens brass fittings. Screwed BSP ends keep installation simple at small bores and allow a valve to be changed with two wrenches. Every size in the range is listed above with its catalogue number and price.
