Catalogue description records
The JWS165 Discharge Valve Assembly is an aftermarket replacement part for the JWS165 mud pump. It seats on the discharge side of the pump's fluid end, where the valve opens on the pressure stroke to let drilling fluid pass downstream and closes to prevent backflow into the cylinder. The JWS165 model number is used for identification and fitment only; this is a replacement part, not an original-manufacturer component.
The discharge valve assembly releases fluid from the fluid end on the pressure stroke and reseats to hold pressure.
