C730 Three-way Control Valve
The C730 Three-way Control Valve is mainly used to divide one incoming fluid into two outgoing fluids, or to combine two incoming fluids into one outgoing fluid. The three-way valve is divided into a combined flow regulating valve (C730-M) and a split flow regulating valve (C730-T). When the nominal diameter and pressure difference are small, the combined valve can be used in the split flow situation, but when the nominal diameter is larger than 80mm and the pressure difference is large, only the split valve can be used.
Special type control valves are customized valve products designed by our company for complex working conditions (such as high temperature, high pressure, strong corrosion, high precision, and low-temperature control, etc.). They possess the ability to precisely regulate flow and pressure, and can meet the stringent requirements in industrial processes.
● Cryogenic temperature regulating valve:
● Adopting elongated valve cover to prevent cold conduction and freezing of packing, thereby eliminating the adverse impact of ultra-low temperature on the sealing performance of the stuffing box;
● Main components undergo hardening treatment, ultra-low temperature treatment, and ultra-precision processing to ensure precise regulation of flow and pressure.
● Passed strict ultra-low temperature deep cryogenic tests to guarantee stable operation under extreme conditions, ensuring safety and reliability.

The globe valve is mainly composed of valve body, valve cover, valve disc and valve stem. The handwheel applies a certain torque at the upper end of the valve stem. The valve stem is passed to the valve petals through the valve stem, so that it moves up and down along the valve stem axis to achieve fully turned on or fully closed movements. The force applied by the handwheel acts on the disc to hold it against the seat to seal. The single disc globe valve is designed to enter the medium by the valve disc sealing surface below, the medium force is opposite to the direction of valve closing, so the valve closing torque is large, so the single disc globe valve is mainly used in low pressure or small diameter pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.
The Lifting Plug Valve adopts a unique dual-action design of lifting and rotation. When opening, it first lifts and then rotates to achieve zero-friction operation. It is particularly suitable for high-pressure difference, easily crystallizing and media containing solid particles. The valve body and the plug are both precisely ground, and the self-cleaning sealing surface design ensures reliable sealing performance under harsh conditions. It is widely used in high-parameter working conditions in the petroleum, chemical and power industries.
Expanding Slab Gate Valve is a type of slide valve that utilizes parallel gate plates as its closing mechanism. These plates are equipped with a spreading mechanism to enhance functionality. The force pressing the plates against the valve seat is regulated by the medium pressure acting on either a floating gate plate or a floating valve seat. In dual gate flat gate valves, the inter-plate spreading mechanism provides additional pressing force. This valve is designed with innovative features including low operating torque, rapid actuation, minimal vibration, extended operational life, and enhanced safety. It is mainly used for the isolation or venting of gases and liquids in pipeline systems.
