Self Operated Pressure Control Valve Boiler Steam

Self-operated pressure control valve consists of a control valve, an actuator and a spring that sets the pressure. Suitable for non-corrosive liquids, gases and vapours, in front of valves in the system piping (when the pre-valve pressure rises, the control valve opens) or after the valve (when the post-valve pressure rises, the control valve closes) pressure control.

Manual Butterfly Valve

Butterfly valve is a common industrial pipe valve, its simple structure, small size, light weight, quick switching, low fluid resistance, is widely used in various industrial fields. The main characteristic of the butterfly valve is that the opening of the valve is directly proportional to the fluid resistance inside the valve, so it can be used to regulate the flow in the pipeline.

Pneumatic O Type Two Piece Flanged Ball Valve

O type cut-off ball valve is a two-piece ball valve structure. The valve body is composed of two parts, the main and auxiliary parts, the seat wear is small, the seal is good, the service life is long, has a strong cutting performance. Ball core adopts full diameter, rated flow coefficient is large, flow resistance is small. Seat limit structure design, maintain torque stability; Lower-mounted stem anti-fly out design, valve seat sealing ring fire-proof, anti-static design.

Pneumatic Segment Ball Valve

Segment valve is a right angle rotary control valve, its main use for regulating valve, can also be used as a switch valve. V-valve spool is designed with special shape V-notch, so it has great shear force and self-cleaning function. Suitable for the control of medium containing fiber or small solid particles. Therefore, this product is widely used in papermaking, chemical industry, petroleum, chemical fiber, electric power, metallurgy, pharmaceutical, environmental protection and other industrial departments of automatic control system.

Fully Forged Gate Valve

The sealing structure of the seat shall be elastic with preload, and the upper and downstream sealing seat shall be sealed at the same time. The seat and the seal are always sealed face to face. The seat shall be made of lubricated, non-abrasive material. Failure of the valve actuator does not affect the rest of the valve, and maintenance and replacement work can be carried out without removing the valve.

Open Rod Flat Gate Valve

The opening rod-plate gate valve adopts the packing structure with self-sealing ability, which does not need to be adjusted. It is very light to open and close, and the sealing is reliable. The packing box is equipped with the auxiliary sealing grease injection structure, which is absolutely reliable in sealing performance, truly achieving zero leakage, and solving the problem that the general valve packing is most likely to leak out.

Cast Steel Gate Valve

The advantage of cast steel gate valve lies in its large diameter, which can meet the requirements of large flow fluid control. In addition, the cast steel gate valve has compact structure, convenient installation and maintenance, and can adapt to fluid control under high pressure and high temperature conditions. At the same time, the cast steel gate valve has good sealing performance, which can effectively prevent leakage and fluid loss. It has a long service life and can run stably under high pressure and high temperature.

Knife Gate Valve

Knife gate valve is mainly used to cut off or control the flow of fluid at low pressure and normal temperature. Its advantages lie in its simple flow channel form, no unnecessary dead corners and turns in the fluid channel, and low fluid resistance, which can effectively reduce the energy consumption and cost of the system. In addition, the knife gate valve has compact structure, convenient installation and maintenance, and can meet the control requirements of various fluids.

Forged Steel Flange Gate Valve

Forged steel flange gate valve belongs to a kind of forging gate valve. The opening and closing parts of gate valve are gate plates. The direction of motion of gate plates is perpendicular to the direction of fluid. According to the sealing surface configuration can be divided into wedge gate valve and parallel gate valve, most of the gate valve is forced to seal, that is, when the valve is closed, to rely on external force to force the gate to the seat, in order to ensure the sealing surface.

Pressure Sealing Gate Valve

Pressure seal gate valve is mainly used to cut off or control the flow of fluid under high pressure and high temperature conditions. The gate of pressure seal gate valve is the main working part of pressure seal gate valve, and the fluid is cut off or controlled by controlling the opening and closing of the gate through the transmission device. The advantage of pressure-sealed gate valve is that its valve seat and gate are under the action of fluid pressure to produce better sealing effect, that is, the greater the pressure, the tighter the seal. In addition, the pressure sealed gate valve has high straightness of fluid passage and low fluid resistance, which can effectively reduce the energy consumption and cost of the system.
