Special Price for Butterfly Control Valve - Cast Steel Pneumatic Operated Soft Seal Knife Gate Valve – Yingzhong

Production Description

● The sealing effect is good, the all-rubber valve plate is adopted, the valve body has no grooves, it is not easy to deposit mud and sand, and the leakage is zero.

● Flexible operation and no leakage, the valve stem is sealed with thrust bearing and “O” ring, which reduces the friction during switching and solves the problem of water leakage in the stuffing box.

● The resistance loss is small, and the valve body is a straight-through type, which reduces the degree of flocculation of the fluid.

● The key parts are made of special materials, which basically require no maintenance and have a long service life.

● The valve adopts novel structural design, strict manufacturing technology and new high-performance materials, which overcomes the defects of traditional gate valve poor sealing, easy corrosion of internal parts, especially the gate, fatigue and aging of rubber elasticity, and reliable sealing performance. Easy operation, simple and convenient maintenance, and long service life.

● Compact structure, reasonable design, good valve rigidity, smooth channel and small flow resistance coefficient

● Good sealing, able to withstand strong pressure, good sealing performance, suitable for gas or fluid with high pressure.

● Easy and flexible operation

● It is widely used in the drainage pipeline system of electric power, hydraulic power, chemical industry and other industries, as the opening and closing system or regulating device to control the flow.

● High quality raw materials. The valve body is made of QT 450-10 material, which is not easy to be pulled and cracked. It will not be broken due to transportation collision and installation.

● Fine craftsmanship. Casting, sand cleaning, machining, assembly, pressure testing, warehousing, and layer-by-layer checks have achieved Seiko’s good quality.

● Valve plate lagging. The valve plate is encased by EPDM rubber, and the glue content is about 50%. The rubber and the ductile iron plate are firmly connected and not easy to fall off, thereby increasing the stability of the valve sealing performance.

Application Area

It is suitable for domestic water system, water supply and drainage system, sewage treatment system, chemical fluid conveying system, etc. It is used as a cut-off device on fluid pipes in construction, urban environmental protection, petrochemical, pharmaceutical, food, metallurgy, textile, electric power and other industries (not for throttling)
