The compact valve is a force-sealing valve, so when closing the valve, pressure must be applied to the valve plate so that the sealing surface does not leak.
What are the characteristics of the use of compact valves?
How does the compact valve work?
What are the design features of the compact valve?
compact valve features lightweight, space-saving design
The compact valve features a unique bolted body and end connections for easy valve removal from the line, simplifying any repairs
Disassembly of the compact valve requires no special tools, and replacement parts are easy to install in the field.
The compact valve has a fire rated design and provides the primary seal at the bonnet and end connections.
compact valve features quarter-turn design
compact valve available as manual lever or actuated
compact valve available in sizes ranging from ½” to 14” (larger nominal sizes available on request)
compact valve with working pressure up to API 20,000 psi
compact valve with bore size conforming to common piping plans
compact valve available in virtually any size and type of end connection
compact valve is one of the most widely used valves. The reason why it is popular is that the friction between the sealing surfaces during the opening and closing process is low, it is more durable, the opening height is not large, it is easy to manufacture and convenient to maintain. It is suitable not only for medium and low pressures, but also for high pressures. The closing principle of the shut-off valve is that the sealing surface of the disc and the sealing surface of the valve seat are close together due to the pressure of the valve stem to prevent the flow of the medium. The valve plays an important role in shutting off and throttling the medium in the pipeline where it is located. The valve plate exerts pressure to close the sealing surface of the valve plate and the sealing surface of the valve seat, preventing the medium from escaping along the gap between the sealing surfaces.
1. Open and close without friction. This function completely solves the problem that the traditional valve affects the sealing due to friction between the sealing surfaces.
2. Top loading structure. The valve installed on the pipeline can be inspected and serviced directly online, effectively reducing device shutdown and reducing costs.
3. Version with single valve seat. The compact valve eliminates the problem that the medium in the valve cavity affects the safety of use due to an abnormal increase in pressure.
4. Low torque design. The valve stem with special structure design can easily open and close the valve with just a small handle.
