Tilting Disc Check Valve

Product Code: MD-VLV-0022

Features: A T-section resilient sealing ring fixed around the outer diameter of the disc seats against the stainless-steel welded seat in the body and provides 100% tight shut-off. | The EPDM, NBR or VITON sealing ring can be removed and replaced easily under site conditions. | Internal and external valve surfaces are coated with 250 µm fusion-bonded epoxy; greater coating thicknesses are available on request. | Self-lubricating bushes reduce friction and provide low operating torque. | High impact resistance. | The double-shaft design minimizes pressure loss. | Shaft extensions on both sides and the counterweight arrangement permit installation in horizontal and vertical pipelines. | The disc opens according to flow velocity and moves freely with the flow. | The adjustable counterweight allows the closing characteristics to be adapted to operating conditions. | Lifting eyes and support feet facilitate handling and installation. | EPDM, NBR or VITON seats selected according to operating conditions can be dismantled and replaced easily on site. | O-rings in the bearing bushes protect the disc pin bores against corrosion (dry-shaft design). | The retaining ring is fixed to the disc with socket-head screws; O-rings beneath the screws protect the disc against corrosion. Applications: Pipelines | Water treatment plants | Pumping stations | Tanks | Seawater applications | Power plants (cooling-water pipelines) | Industrial applications
