The Tilting Disc Check Valve is an excellent choice for raw water, cooling water and treated water/wastewater applications. Its streamlined body contouring, flow area 40% greater than nominal pipe size and hydrodynamic disc combine to provide the lowest headloss of any check valve produced today
Swing valve is a butterfly-style check valve in which the disc, the movable part to block the flow, swings on a hinge or trunnion, either onto the seat to block reverse flow or off the seat to allow forward flow. The seat opening cross-section may be perpendicular to the centerline between the two ports or at an angle.Although swing check valves can come in various sizes, large check valves are often swing check valves.
dual-plate check valves are wafer-type valves with a short overall length. Their excellent hydrodynamic properties result in very low pressure losses. Their lower weight brings advantages during installation, transport and storage.
They are suitable for liquid, gas and steam in heating, air conditioning and cooling systems. However, they can also be used in steam and condensate systems, in the water supply, and in oil and natural gas pipes.
With the suitable springs, they can be installed in any position.
High pressure power station check standards:
1. The design and manufacture and acceptance by thermal power valve standard ANSIB16.34 API6D GB12236 E101 and JB/T3595, DL/T531 prescribed standards.
2, the structure length by E101, JB/T2766, GB/T15188.1 ANSIB16.10 GB12221 standard or according to user requirements.
3, pressure - temperature level by E101, JB/T3595 API598 GB9131 prescribed standards.
4, according to the welding groove size GB12224, JB/T3595, ASME B16.25 ANSIB16.25 standard rules or according to the size of the user piping requirements
Pressure Seal Tilting Disc CHECK VALVE The Tilting Disc Check Valve is also called equilibrated disc non return valve and it is coupled with on-off valves in high pressure lines to protect the system from the fluid reversing flow when regular flow is stopped .
