Q641 pneumatic regulator ball valve is mainly used to cut off or connect the media in the pipeline can be used for fluid regulation and control. With excellent sealing performance, flow coefficient, flow resistance coefficient, simple structure, long life, easy maintenance and so on. Pneumatic adjustable ball valve range of applications: Q641F / PPL-type pneumatic ball valve is a rotary angle of 0-90 ° rotary valve, excellent sealing performance, flow coefficient, flow resistance coefficient, simple structure, long service life, easy maintenance . Equipped with a cylinder-type actuator, the ball valve into a single role and double-acting two models. Pneumatic Positioning Ball Valve Products are widely used in chemical, petroleum, textile, electricity, food pharmaceuticals, refrigeration, paper industry system control. Structural features of the ball valve: 1. Fluid resistance is small, the ball valve is the smallest of all fluid resistance in a valve, even the reduced diameter ball valve, the fluid resistance is quite small. 2. Thrust bearings to reduce the valve stem friction torque, valve stem long-term operation can be balanced and flexible. 3. Seat sealing performance is good, the seal made of PTFE and other materials, the structure is easy to seal, and ball valve sealing capacity increases with the media pressure increases. 4. Stem seal is reliable, as the stem only for rotary motion without lifting movements, stem packing seal is not easy to damage, and the sealing capacity increases with the media pressure increases. 5. Due to PTFE and other materials with good self-lubricating, and the friction loss of the ball is small, helping the long service life of the ball valve. 6. Bottom stem and valve stem convex step to prevent the stem ejected, such as a fire caused by stem seal damage, convex step and the body can also form a metal contact between the stem to ensure that the seal.
Stainless steel Basin Faucet is a faucet made of stainless steel. Stainless steel is a healthy material, without lead, acid, alkali, corrosion resistance, does not release harmful substances, can ensure human health and hygiene. Stainless steel basin faucets are safe and lead-free, with no corrosion, exudate, or odor or cloudiness issues. It will not cause secondary pollution to the water quality, keep the water quality pure and hygienic, and fully guarantee the health and safety. Field corrosion test data show that stainless steel has a service life of up to 100 years and requires almost no maintenance during the life cycle, avoiding the cost and trouble of faucet replacement and low operating costs. Achieve the same service life of the stainless steel basin faucet as the construction.
