Catalogue description records
This Safety / Relief Valve is the 3-inch valve core component (阀芯) for a mud pump safety/relief valve, supplied with a square-flange connection in imperial specification (方法兰、英制) per the original part name. As a safety/relief valve element, it is part of the pump's pressure-protection circuit, opening to release fluid when pressure rises beyond the set point. The 3-inch (3寸) size identifies the connection. It is offered as an aftermarket replacement part; any model or part references are for identification only.
A safety/relief valve limits system pressure by opening when a set pressure is exceeded.
