No. the lift check valves can only be mounted on horizontal pipelines.
The main advantage of the lifting check valve is its simple structure. Since the cone valve is the only moving part, the valve is durable, and it is hard to maintain, and because it is a metal valve seat, it is very small. The limitations of the lifting check valve must be installed on the horizontal pipe.
With a metal-sealing sub-check valve, a small amount of leakage is allowed to be used in cases only for the fluid backflow seal requirements, generally only for the water system, and thus commonly used to prevent the condensed water of the steam. Backflow, also used for the exit of the condensate pipeline from the center of the pump.

Both lift type check valves flanged end and swing type's material can be CI/DI/WCB/SS
Both lift type check valves flanged end and swing type's pressure can be Class150/300/600/900, PN10/16/25/40/63,5K/10K/16K
Stardard: DIN 3202 PN10/16, ANSI CLASS 125/150
Face to face: DIN 3202 F1, MSS-SP-85
Connection flange type: Flange end
The disc of lift type flanged End check valves is vertical to the body, fluid resistance coefficient is slightly larger than swing check valves. Horizontal installation as with all check valves.
No. the lift check valves can only be mounted on horizontal pipelines.
(1) The lift check valve has a simple structure, reliable operation, and convenient maintenance. It is widely used in purification equipment, petroleum, chemical and other production operations.
(2) The unique design can automatically open and close the valve to prevent fluid backflow.
(3) The disc of the lift check valve is usually in the shape of a disc, usually rotating around the center of the valve seat. In addition, since it moves vertically along the center line of the valve body during operation, it forms a streamline in the channel inside the valve, and the flow resistance becomes very small
