BNSV Resilient gate valve

Overview

The soft seal gate valve uses the compensation function of elastic deformation produced by the integral rubber coating of the gate to achieve good sealing effect, and overcomes the phenomenon of poor sealing, water leakage and rust of the traditional gate valve. It is widely used in tap water, sewage, building and other fluid pipes, and plays the role of maintenance, switch and evacuation.

● Full diameter flat bottom channel. Full channel straight through design, low flow resistance, flat seat is not easy to accumulate debris.

● Integral rubber covered ram. The whole ram is vulcanized with rubber, and the rubber is firmly bonded to the ram framework without degumming.

● Stainless steel stem rolling thread. Stainless steel corrosion resistant stem, thread rolling forming, smooth and wear-resistant, low operating torque, long service life.

● There is no leakage. Three "O" ring seal, compared with traditional packing, has higher sealing reliability, smaller switch friction resistance, more environmental protection and hygiene.

● It is environmentally friendly and non-toxic, and can be used in direct drinking water system. The inside and outside of the valve body is sprayed with environment-friendly and non-toxic epoxy resin. The gate plate is fully covered with high-performance food grade rubber. All parts in contact with water will not cause pollution. It can be used in drinking water, food and pharmaceutical industries.

● Bidirectional sealing. The flow direction of the medium is not limited, and the two-way sealing can be realized.
