Our aim is providing stable quality, stable service, establishing stable relationship with you!
If you want to check our products quality lever, we can provide you sample for checking. Which will help us to get a start.
We provide not only standard valves but also develop new pattern according to custom design ideal. Our O&D team will also give you good advice on design.

Standard size plywood box
Some small pieces like fire hydrant, we use standard size plywood box to pack.
Custom Plywood box
Custom box according to the size of valves to make sure the packing is more strong.
Delivery to port
We will make sure all the box loaded in right way to avoid the damage of box before loading in container.
Custom Plywood box
Custom box according to the size of valves to make sure the packing is more strong.
During winter construction, water pressure test is carried out under negative temperature.
Consequences: due to the rapid freezing in the tube during the hydraulic test, the tube was frozen
Ordinary gate valves, ball valves, and globe valves are strictly prohibited for adjustment due to their structural characteristics. But in process design, it is generally used for mediation. Due to the adjustment and use, the valve seal is in a throttling state for a long time, and the impurities in the oil wash out the seal and damage the sealing surface, resulting in lax closing or the operator has damaged the sealing surface to achieve the seal, cause the valve to be over-closed and over-opened
1.Clarify the purpose of the valve in the equipment or device, and determine the working conditions of the valve: applicable medium, working pressure, working temperature, etc.
2.Determine the nominal diameter and connection method of the pipeline connecting with the valve: flange, thread, welding, etc.
Differential pressure usually refers to the pressure difference between two points of the valve in the pipeline, such as the pressure difference between the front and back of the valve, the pressure difference between the two sides of the double flange, and so on.
Wafer butterfly valve is one of the most common types of valves in industrial pipelines. The wafer butterfly valve itself has a relatively small structure. You only need to put the butterfly valve in the middle of the flanges at both ends of the pipeline, and use stud bolts to pass through the pipeline flange and butterfly valve is locked to control the fluid medium in the pipeline. Wafer butterfly valve is especially suitable for places with narrow space or short distance between pipelines. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body.
Under the following working conditions, butterfly valves are recommended:
①Require throttling, adjustment and control flow;
②Mud medium and medium containing solid particles;
③Occasions where the valve structure length is required to be short;
④Occasions requiring fast opening and closing speed;
⑤Occasions where the pressure difference is small.
