Check Valves

Kent Check Valves are heavy duty, bolted covers, renewable seat ring, internally body mounted disc arrangement. These valves are unidirectional and restrict flow in the opposite direction. These valves are best suited for moderate velocity conditions. Check valves are normally designed for horizontal flow conditions but can also be installed in vertical pipelines, but in vertical pipelines, the flow should be in an upwards direction and under the disc.

Kent Check valves are heavy duty, bolted cover, renewable seating ring, internally body mounted disc arrangement.
Check Valve design complies to BS EN 1868, ASME B 16.34.
Cast body precisely machined with integral flanges.
Cast cover provides easy access to the disc and hinge without removing the valve from the pipeline in case of maintenance.
Disc is ground and lapped for better finish and sealing. The disc is integrally guided to assure true alignment between disc and valve body. The loose disc allows for proper sealing without damage.
Hinge pin is precisely machined and mounted on the body internally.
Hinge is pivoted to the hinge pin inside the body.
Disc nut secures the disc to the hinge. It allows the disc to rotate about its axis and assist in tight shut off.
Seat rings are welded in or integral to provide bubble tight joint.
Swing check valves can also be provided with Dashpot and counter weight arrangement on request.
Fire Safe – By design and tested to API 607/ ISO 10497.
CE Marking – Meets requirements of Pressure Equipment Directive 2014/68/EU, Annexure III, Module H.

• Integral body seat. In-situ hard-facing provided for Trim 12 and 16 valves.
• Integral hinge design eliminates additional leakage path.
• Body-bonnet Joint – Class 150 Globe Valves offered with square-shaped body-bonnet joints in size 2” and with oval-shaped joints in 3” size. Valves in all other sizes and pressure classes offered with circular body-bonnet joints.
