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.
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 inch 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.
