Application
The opening and closing member of the national standard stop valve (throttle valve) is a cylindrical valve flap with a flat or conical surface, and the valve disc moves linearly along the center line of the fluid. The national standard stop valve is only suitable for full opening and full closing. It is generally not used to regulate the flow. It is allowed to adjust and throttle when customized.
Globe valves are commonly used as an on/off valve, but they may be used for throttling systems. The gradual change in spacing between the disk and seat ring gives the globe valve good throttling ability. These linear motion valves can be used in a variety of applications as long as the pressure and temperature limits are not exceeded, and the process does not require special materials to combat corrosion. Globe valve also have a smaller chance of damage to the seat or valve plug by the fluid, even if the seat is in the partially open position.

Feature
1. Advanced structure, reliable sealing, excellent performance and beautiful appearance. The steel of the valve stem is increased, the noise and vibration are significantly reduced, and the service life and performance of the valve are improved.
2. The shut-off valve can be installed at any position of the pipe, and the medium flows from the bottom to the top.
3. DN250 or above adopts advanced multi-sealing, double brackets, adopts guiding motion (which can greatly improve the impact resistance against water hammer), and the medium enters from above. It better solves the large opening and closing torque of the large-diameter globe valve, and the seal cannot be closed. The filling chamber runs, which greatly improves the performance and scope of the valve. (The torque of "off" is 10% of the "open" of the ordinary valve is 3% of the ordinary valve).
4.Higher pressure drop compared to a gate valve.
5.Large valve sizes which require considerable power or a larger actuator to operate.
