Gate valves(Ball Screw operation)

Gate valves(Ball Screw operation)


The Ball-Screw operation gate valve was developed for large-bore applications,to provide manual operation at full working pressure with remakably low opening torque.The design eliminates the need for gear-type torque multipliers,and results in quicker,safer operations.
The Ball-Screw operation gate valve shares the basic features of the "LS"series:a slab gate,patented seat seal,non-elastomeric stem seals,and metal-to-metal sealing.However,the Ball-Screw operation gate valve has a lower balancing stem and unique ball Screw mechanism

CHECK VALVE


CHECK VALVE


Check valve creates the metal-to-metal seal by the pressure of the medium, the more the pressure is, the better the sealing effect is. Anytime the valve chamber can bear the pressure of the pipeline.The sealing face between valve core and valve body is welded with hard alloy with good abrasion resistance and anti-scour; the valve core is made of sulfide-resistance steel and the others adopt the process of hardness limit so the valve is able to be used in H2S condition.

Gate valves

Gatevalves


Gate valves are forged from alloy steels, gate valve can be open by lifting a round or rectangular gate/wedge out of the path of the fluid.
Bonnets provide leak-proof closure and pressure seal for the valve body; such construction is adopted for valves for pressure exceed 15 MPa (2250 psi). The unique feature about the seal bonnet is that the body bonnet-joint-seal improves as the internal pressure in the valve increases, compared to other constructions where the increase in internal pressure tends to create leaks in the body-bonnet joint.

Specification
2"×40MPa

Needle Valve

Needle Valve


Needlevalve has a long tapered point at the end of the valve stem. Needle valve is more suitable as a throttle valve. Needle valves are used to control flow into delicate gauges, which might be damaged by sudden surges of fluid under pressure. Needle valves are also used to control the end of a work cycle, where it is desirable for motion to be brought slowly to a halt, and at other points where precise adjustments of flow are necessary and where a small rate of flow is desired. Many of the needle valves used in fluid power systems are manually operated; this valve is constructed with a hand-wheel and is adjusted to provide a specific rate of flow. This rate of flow will provide a desired time of operation for a particular subsystem. Since this of valve can be adjusted to conform to the requirements of a particular system, it can be used in a variety of systems.
Needlevalves are available in forged model or cast model, specifications for needle valves are as follows:
