Bolted Cover Check Valve

A bolted cover check valve is a highly serviceable, automatic non-return valve designed with a heavy-duty bolted flange cover that allows rapid access to the internal swing disc or piston assembly for inline cleaning and maintenance. Operating strictly via fluid pressure differentials, the internal disc swings or lifts open under forward flow and snaps shut under gravity or backpressure to prevent reverse flow and protect upstream pumps. The robust bolted bonnet design uses a high-integrity gasket to seal against high pressures while ensuring that technicians can perform routine inspections directly on-site without cutting the valve out of the pipeline. Water utility operators and pipeline maintenance contractors can simplify routine servicing and safeguard pumping assets by importing certified bolted cover check valves directly from leading manufacturers in China via our advanced B2B digital marketplace.
