Features of rising stem gate valve:


Light weight: The body is made of high-grade nodular black cast iron, which is about 20% to 30% lighter than traditional gate valves, and is easy to install and maintain.


Flat-bottomed gate seat: The traditional gate valve often deposits in the groove at the bottom of the valve due to foreign objects such as stones, wood, cement, iron filings, sundries, etc. After the pipe is flushed with water, which can easily casue water leakage due to failure to close tightly. The bottom of the elastic seat-sealed gate valve adopts the same flat-bottom design as the water pipe machine, which is not easy to cause debris siltation and makes the fluid flow unimpeded.


Integral encapsulation: The gate adopts high-quality rubber for integral inner and outer rubber. European rubber vulcanization technology enables the vulcanized gate to ensure accurate geomatric dimensions, and the rubber and ductile cast gate are firmly connected, not easy to fall off and elastic good memory.


Precision casting valve body: The valve body adopts precision casting, and the precise geometric dimensions make the inside of the valve body without any fine machining to ensure the sealing of the valve.
