Chief Features

The structure design of elastic sealing ring has been adopted for floating ball valves. This seat design features is a bigger sealing pressure ratio between the ring surface and the ball when medium pressure gets lower where the contacting area is smaller, thus the reliable seal is ensured.when the medium pressure gets higher, the contacting area between seat ring and ball becomes bigger as the sealing ring transforms elastically to under take the bigger force pushed by the medium without any damage.

A variety of soft seal and hard seal seat materials to meet more process conditions

The optimized limiting device further improves the accuracy of the valve passage and the flow CV control

ISO platform can be selected to facilitate the operation of the actuator

The valve meets NACE standard, fugitive emission function and fire test certification of API Spec 607

Chief Features

Compared with floating ball valve, when working, all the forces generated by the fluid pressure in front of the valve on the ball are transmitted to the bearing, which will not make the ball move towards the valve seat, so the valve seat will not bear excessive pressure.And the torque of trunnion ball valve is small, the valve seat deformation is small, the sealing performance is stable, and the service life is long, which is suitable for high-pressure and large-diameter occasions. Advanced spring pre-seat assembly with self-tightening feature realizes upstream sealing. Each valve has two seats, which can be sealed in each direction. Therefore, there is no flow restriction for installation, and it is bi-directional. The valve is generally installed horizontally.

A variety of soft seal and hard seal seat materials to meet more process conditions

According to your requirement the valve can meets NACE standard, fugitive emission function and fire test certification of API Spec 607

The seat can be designed with double or single piston and has lower operating torque

All valves have self cavity pressure relief function to ensure the safety of the pressure in the middle chamber

Chief Features

The specially designed V-shaped ball has strong shearing effect and sealing performance on the medium, and can adjust the flow characteristics of the medium in equal proportion

The valve meets NACE standard, fugitive emission function and fire test certification of API Spec 607

API 622 certified live loading of packing makes valve stem sealing safer

The spherical surface can be hardened by hard chromium plating, desalination, supersonic spraying and other sealing surface hardening processes to increase the hardness, wear resistance and corrosion resistance of the sealing surface

The valve seat spring is designed with clip spring, which can provide preload for the valve seat seal and greatly reduce the torque required to drive the valve

Due to the shear force between the V-shaped opening and the valve seat, and the smooth and round flow channel in the valve cavity, the medium is not easy to accumulate in the cavity, so it is more suitable for the system control of medium with fiber and solid particles besides liquid medium

Chief Features

3-pc ceramic ball valve is a valve that the ball rotates around the body center line to control on-off, and only trim part adopts ceramic material, It mainly used for quickly cut, distribute and change the direction of the flow medium in pipeline.

3-pc ceramic ball valve can close tightly only need rotate 90°with small torque. The full port body cavity provided little resistance,with straight flow channel. It suitable for water treatment, gas pipeline, steam boiler, lime slurry, textile, particles seawater medium etc.with characters like compact structure, easy operation and maintenance.

The ball is made by advanced grinding equipment and advanced process technology that can ensure high precision ball roundness. The self-lubricating capability of ceramic ensures the good sealing after polishing,which radically changed the defects that metal hard sealing valve has such as big torque, non-corrosion-resistant sealing surface.

Ceramic valve adopts new high-tech structural ceramic material as sealing and wearing parts, which can improve abrasion, corrosion resistance, and sealing performance, prolonging lifespan,2-4 times of lifespan than Titanium Alloy and Monel valve. Using ceramic valve can reduce repair or replacement costs and improve safety,stability of operating system.
