Shipping & Delivery:	20-25 days lead time; deliver by ship from Ningbo port or Shanghai port
Driving element type	Hydraulic actuator
Notes: Serial valve connecting flange and butt-welding terminal size can be designed at customers'request. The material of the main parts and sealing surface of the valve can be designed and selected according to the actual working conditions or the special requirements of users.

 

 

1. Simple structure, compact, small size;

2. Smooth and reliable transmission;

3. Can obtain a large output torque;

4. The output torque can be accurately adjusted through the constant pressure relief valve, including the adjustment of the opening and closing torque, and even can be directly reflected through the hydraulic instrument;

5. Easy speed adjustment;

6. In the event of sudden power failure, the accumulator can still be used for one or several power operations. This is of special significance to the automatic emergency cut-off valve and wellhead blowdown valve of long-distance transmission pipeline.

Q: What is the material of the valve?

A: We can advise you to choose according to your needs or configure according to your requirements.

 

Q: What kind of packing and shipping will be used?

A: We will pack and ship according to your specific requirements.

 

Q: What are the disadvantages of hydraulic valve equipment?

A:

1) The oil temperature is greatly affected by the ambient temperature, and the change of oil temperature causes the change of oil viscosity and affects the operation;

2) Troublesome piping, easy to produce leakage;

3) It is not suitable for generating various operations on the signal (such as signal amplification, memory, logical judgment and other operations). Hydraulic valve device has its advantages and shortcomings, we should know how to develop strengths and avoid weaknesses in the use of the process, both to give full play to its advantages, but also to avoid the loss caused by shortcomings.

 

Q: Are convex and concave flanges connected to valves often made of convex or concave?

A: The convex and concave flange connected to the valve is often made of concave.

 

Q: What is the purpose of designing valve reverse seal seat?

A: After the valve is fully opened, the inverted cone of the stem head is consistent with the upper sealing surface of the valve cover, and the medium in the valve chamber is blocked from leaking through the packing box. Its function is:

1. In the case of the valve is normally open, because the direct effect of the medium on the packing is blocked, so as to protect and improve the sealing performance of the packing.

2. Under special crisis conditions, the filler can be replaced with pressure to avoid device shutdown, causing unnecessary losses.

 

Q: When low-temperature valve does low-temperature impact test, what sample is made according to?

A: When the low-temperature valve is tested at low temperature, the sample is made according to the V-shaped impact test sample.
