Gate valve design features
Wedge gate valve Design
The wedge gate valve design uses a flexible disc to achieve precise alignment of the seat surface and a tight seal that cannot be achieved with other standard wedge gate valves.
Pressure sealing valve cover
There are no solder joints, gaskets or gaskets between the pressure sealing valve cover and the valve body. This structure is simple and effective. The integrity of the connection between the valve body and bonnet is achieved through numerous thermal cycle tests.
High performance packing system
Packing system has the best performance. The single packing gland can be adjusted at any time through the integral gland wrench. The valve stem and packing cavity are processed with precision graphite packing, which has good performance and greatly extends the service life of the packing.
Single Gland
The simpler the design and the fewer parts, the better the performance of the valve in harsh environments. Durable one-piece stainless steel gland ensures valve longevity.
Axial Load Packing System
The axial design ensures high concentricity while eliminating the side load of the packing and reducing wear on internal components of the valve. This design feature is critical to the valve's superior performance.
Pressure type upper seal
d Pressure type upper seal greatly improves the integrity of the valve and ensures that the valve stem and valve core assembly are accurately in the proper position. The pressure-type upper seal protects the packing from pipeline pressure when the valve is fully open, thereby extending the service life of the packing.
Quick online repairability
Gate valves are easier to repair than any valve on the market. d Gate valve online maintenance provides modular solutions which will lead to an increase in maintenance costs. Low valve acquisition cost is less important than low life cycle cost. Maintaining valves is far easier and less expensive than replacing competitor valves
