Knife Gate Valve

Knife Gate Valve

【Introduction】:
A Knife Gate Valve with spool made of wear-resistant rubber developed by international advanced technoloy
【Pressure】:
1.6MPa/cm2
【Improvement】:
High resilience of rubber liners of valve, tight combination between gate valve and disc, guarantee the sealing

【Advantages】

Rubber spool is produced with " liquid phase nanometer compounding, normal temperature high-frequency curving". Wear-resistant index id over 128% and its service life is 2-4 times longer than ordinary valves under the same working conditions. Xinhai wear – resistant rubber as liners of knife gate valve owns high resilience up to 86% and high sealing performance, no leakage Simple structure, convenient operation and maintenance No pressure lose

【Product Structure】

Xinhai knife gate valve is mainly manual gate valve. Xinhai can also manufacture electric and pneumatic gate valve according to the needing of customers. The three kinds of gate valve can be carried out by remote control. In addition, the valve body is fitted with oil nipple to reduce the friction on gate and force moment of opening and closing of the valve. Spool made of wear – resistant rubber, small specific gravity, easier to replace

【Successful case】

Several mineral processing plants in Yunnan and Guangxi chose Xinhai as their knife gate valve manufacturers, it is lined with unique wear-resisting rubber that is developed by nanometer technology, also called super thin knife gate valve. The equipment of Xinhai knife gate valve manufacturer shows that the valve line index is more than 128% after testing, the wear-resistant elastic is above 80%, the gate valves combined with gate plate together closely without leakage, its service life is as 2-4 times as other knife gate valve, the plugging rate of discharge opening is almost zero, no pressure loss, which is favored by customers.
