Our goal: to be a high-quality manufacturer of industrial control valves, gaining unanimous recognition from new and old customers
Our mission: To fully utilize the effectiveness of industrial control valves to achieve better results
Pneumatic ball valves are divided into O-type ball valves and V-type ball valves. "The O-type ball valve adopts a floating structure, with a precision casting core and a hard chrome plated surface. The valve seat is made of reinforced polytetrafluoroethylene material. The flow port has the same diameter as the pipe, with great flow capacity, minimal flow resistance, and no leakage when closed. It is generally used as an on-off valve. It is particularly suitable for high viscosity, V-type ball valves with a fixed structure. The ball core has a V-shaped notch, which can shear fibrous and granular media.".
According to different process equipment, pneumatic or electric actuators can be selected to form pneumatic ball valves and electric ball valves, respectively. For pneumatic ball valves to achieve proportional adjustment, valve positioners must be equipped. For electric ball valves to achieve proportional adjustment, electronic electric actuators or servo amplifiers must be selected.
In terms of material, it can be divided into: carbon steel ball valve, stainless steel 304 ball valve, 316 ball valve, and copper ball valve
According to pressure, it can be divided into high-pressure ball valve and low-pressure ball valve
High pressure pneumatic ball valve: mainly used in oil, natural gas, hydraulic oil, construction machinery and other industries
Low pressure pneumatic ball valve: mainly used in corrosive pipelines with water as the medium! Precautions and models for the use of knife type gate valves: The opening and closing part of knife type gate valves is a gate, and the movement direction of the gate is perpendicular to the direction of the fluid. Manual knife type gate valves can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the commonly used mode gate valve form a wedge shape, and the wedge angle varies depending on the valve parameters, usually 50. The gate of the wedge knife type gate valve can be formed as a whole, called a rigid gate; It can also be made into a gate that can produce slight deformation to improve its processability and compensate for the deviation in the angle of the sealing surface during processing. This gate is called an elastic gate knife type gate valve. When closing, the sealing surface can only rely on medium pressure to seal, that is, rely on medium pressure to press the sealing surface of the gate towards the valve seat on the other side to ensure the sealing surface is sealed, which is self sealing. Most knife type gate valves use forced sealing, that is, when the valve is closed, external forces must be used to forcibly press the gate plate against the valve seat to ensure the tightness of the sealing surface. This type of valve should generally be installed horizontally in the pipeline.
