vacuum cast steel gate valves, cast steel casting process of a kind of vacuum gate valve, according to its form of connection flange, welding can be simply divided into two kinds, drive mode, which has two kinds of manual and electric. Vacuum isolation gate valves is suitable for the working temperature & le; 425 ℃ and & le; 550 ℃, working medium is water, steam, oil, and the corrosion of gas pipeline for opening and closing device. Particularly suitable for power plant turbine condenser and vacuum negative pressure system, the vacuum insulated sealing function.

vacuum gate Industrial Valves, gb gate valves, cast steel gate valve type, according to the configuration of sealing surface can be divided into wedge type gate valve and parallel sluice gate valve gate, wedge gate valve gate can be divided into: single gate type, double disc and flexible disc; Parallel slide gate valve can be divided into single ram and double ram. According to the threads of the valve stem position, can be divided into rising stem gate valves and dark bar gate valve two kinds.

vacuum gate valve is closed, sealing surface can only rely on medium pressure to seal, that depend on medium pressure, the disc will be to the other side of the valve seat sealing surface pressure to ensure that the seal face seal, this is the seal. Most is adopt compulsory seal gate Industrial Valves, the valve is closed, to rely on outside force forced the ram pressure to the seat, to ensure the sealing surface sealing.

vacuum gate valve gate, linear motion, with the stem called lifting lever gate ( Also called rising stem gate valves) 。 Usually in lifting lever on the trapezoidal thread, through the valve at the top of the nut and guide groove on the Industrial Valves body, the rotation movement into linear motion, which is the operating torque thrust into operation.

open valve, when the gate hoisting height is equal to valve size 1:1 times, fluid channels open completely, but at runtime, the position cannot be monitored. Actual use, is the stem apex as a sign, that is fixed position, as its full open position. To consider locking phenomenon in a temperature change, usually in the open to the vertex positions, pour 1/2 - back 1, as the full open position of the valve. The valve fully open position, therefore, according to the location of the damper ( The itinerary & gt; To determine. as a domestic high-end valve manufacturer, always respond to national policy and called for, committed to researching, developing and manufacturing electric butterfly valve, stainless steel ball valve, discharge valve, electric gate valves, stainless steel gate, stainless steel valve, stainless steel check valve, high pressure gate valves high-quality let customer trust of good valve, the valve to keep traditional valve product sales profits to escort for the innovation research.

Shenzhen Mech Valve Trading Co., Ltd. will continue to build a corporate culture that respects and values the unique strengths and cultural differences of our associates, customers and community.
Helping our customers manage document workflow and increase efficiency through best-in-class gate valve and services. Fostering the growth and development of our employees.
Overall, wedge valve may be a great way for manufacturers to expand their use of technology, but the price could present a significant hurdle for some businesses.
Increasing consumer awareness and rising concern about improving cast iron gate valve are driving the market of products.
