Z61H self-sealing forged steel gate valve Product Overview
Z61H Self-sealing forged steel gate valve is designed and manufactured in accordance with API602 and ASME B16.34. Inspection and testing per API 598, marking by MSS-SP-25. Cardiac pressure plate bolted design and manufacturing in line with API602 and ASME B16.34.
Z61H self-sealing forged steel valve Product advantages:
1, the fluid resistance is small, the sealing surface of the medium by the brush and erosion of small.
2, opening and closing more effort.
3, the medium flow is not restricted, does not disturb the flow, does not reduce the pressure.
4, the shape is simple, the structure of short length, manufacturing technology is good, a wide range of applications.
Z61H self-sealing forged steel valve Disadvantages:
1, sealing surface easily lead to erosion and abrasion, maintenance more difficult.
2, the larger size, open the need for a certain space, open and close a long time.
3, the structure is more complicated.
Z61H self-sealing forged steel gate valve parts and components of the material
Self-sealing forged steel gate valve installed to use:
1, Before installing the valve cavity and sealing surface to be checked and other parts, do not allow dirt or grit attached;
2, the bolts of the connection parts, require uniform tightening;
3, check the packing parts require compression, both to ensure that the packing seal, but also to ensure that the gate open flexible;
4, the user before installing the valve , the valve must be proofing the model, connecting size and pay attention to the flow of media to ensure consistency with the requirements of the valve;
5, the user installs the valve, must reserve the necessary space that the valve drives;
6, the wiring of drive device shall be carried out according to the circuit diagram;
7, gate valve must be regularly maintained, not free to crash and squeeze, so as not to affect the seal.
