1. The valve seat adopts an O-ring seal and a floating valve seat structure with pre tightening force applied, which makes the inlet and outlet of the flat gate valve sealed in both directions; And the opening and closing torque of this structure is only half of that of a regular valve, which can easily open and close the valve
2. When fully open, the channel is smooth and straight, with minimal flow resistance coefficient and no pressure loss. It can clean the pipeline with a capillary ball
3. Adopting a packing structure with self sealing ability, without the need for frequent adjustment, the opening and closing are extremely lightweight, and the sealing performance is reliable. There is an auxiliary sealing grease injection structure at the packing box, which is absolutely reliable in sealing performance and truly achieves zero leakage; Solved the problem of leakage at the packing of general valves
4. When the flat gate valve is closed, it can automatically remove the high pressure inside the chamber, ensuring safe use
5. Fully enclosed structure, good protective performance, and can adapt to all-weather requirements
PFFW rising stem flat gate valve is a high-performance, bi-directional sealed concealed stem gate valve. Integral forging forming, with excellent performance in high-pressure environments, can be applied to oilfield wellheads, Christmas trees, gas trees, and manifold systems ranging from 2000psi to 20000psi.

PFFA plate manual gate valves are available in a variety of sizes and pressure ratings to meet different industrial requirements. Whether you need a valve for a small-scale operation or a large-scale industrial process, we offer a variety of options to meet your specific needs. Our valves are equipped with a handwheel operating mechanism for easy manual control and operability, ensuring efficient fluid regulation.
PFFA Slab Gate valves are widely used at wellhead equipment, christmas tree, manifold plant equipment and pipelines. Full-bore design, effectively eliminate the pressure drop and eddy current, slow flow of solid particles in the valve. Between bonnet & body and gate & seat are adopt metal to metal seal, between gate and seat are adopt metal to metal seal, surface spraying (heap) welding hard alloy, has good abrasion resistance, corrosion resistance. Stem has back seal structure so as to replace seal ring of stem with pressure. There is a seal grease injection valve on bonnet so as to repair seal grease and provided seal and lubricate performance of gate and seat
It is match with all kind of pneumatic (hydraulic) actuator as customer's requirement.
PFFA plate manual gate valves are designed with user convenience in mind for worry-free operation, reduced downtime and increased productivity. Low-friction stem packing minimizes the need for frequent maintenance, ensuring smooth and reliable performance over the long term. Additionally, these valves feature a concealed stem design that allows for compact installation while maintaining optimal functionality.
