Description of 8 Inch Gate Valve:

The internal parts of ZECO 8 inch gate valve are made by the technology department to choose the most corrosion resistance and wear resistance of the material for production, to ensure that all kinds of corrosive medium in various pressure various temperature environment pipeline safety operation for a long time, of course, can also according to the actual needs of users and requirements for production, internal parts material ZECO can provide stainless steel internal parts, duplex stainless steel internal parts and low-temperature steel internal parts to meet the needs of different working conditions. For some special working conditions, ZECO can provide users with a complete set of pipeline valve solutions, so that users can leave the design of valve system to ZECO and deal with other pipeline problems by themselves.

Features of 8 Inch Gate Valve:

1. The handwheel of ZECO 8 inch gate valve is exposed for a long time, which may cause rust damage and need to be replaced. Considering this problem, ZECO designed the handwheel to be removable when the valve is fully open and ensured that the gate is in the open position. In addition, ZECO can also adopt painted handwheel to ensure anti-corrosion of handwheel;

2. ASTM A194 2H and ASTM A193B7 nuts and stud bolts for normal service conditions.ZECO provides ASTM A194 4 and ASTM A193B16 nuts and stud bolts or higher configurations if specified for use at high temperatures. ZECO stainless steel valves are furnished with standard bolts from ASTM A194 8 and ASTM A193 B8 nuts and studs;

3. The valve stem of ZECO 8 os&y gate valve is designed to prevent blow out of the valve stem, which is designed to prevent people from injury caused by flying out of the valve stem due to internal pressure problems when people need to replace packing or other parts with pressure in an emergency;

4. ZECO 8 inch gate valve can be produced to 150 ~1500 lb, safe and reliable.

Strainers, dirt separators and backflow preventers are designed to prevent impurities from entering the specified pipe section. Comparing these three types of products, we can analyze from the following points: first, flow resistance. Many manufacturers tend to ignore this point and push the performance of the product to push the product's practicality. However, if the flow resistance fails to meet the requirements, and there will be impurities in the later stage, the flow resistance will be larger and larger, especially affecting the energy consumption, thus the gain is not worth the loss.

The flow resistance of ZhengFeng's products is tested by the third-party testing center in China to achieve the best product status and reduce the daily operating costs of customers; Second, the filter core material. If used in medium for a long time, the filter core material shall have a long life, which can prevent frequent replacement and the risk of secondary pollution caused by corrosion of the filter core being washed away; Third, filtering performance.

This is also a point that will be paid attention to. According to the customer's working conditions, ZhengFeng can customize a special filter to achieve the use effect; Fourth, discharge function. In the market, the function of sewage discharge is often neglected, and some manufacturers may only consider the part of filtration function while missing the part of timed emission. All sorts of surprises are hard to predict, apart from the human cost, if cleaning is required. Therefore, the filtering products of ZhengFeng have additional sewage discharge devices, such as y strainer with drain valve, magnetic y strainer, magnetic dirt separator, etc., to meet the requirement that customers can easily open the device outside the valve and clean the impurities inside the valve without removing the valve.
