Even if installation is temporarily difficult, the long-term work of operators must be considered. It is best for the valve handwheel to be level with the chest (usually 1.2 meters above the operating ground) for easier opening and closing of the valve. The handwheel of the floor standing valve should be facing upwards and not tilted to avoid smooth operation. The valves of wall mounted equipment should also leave space for operators to stand. Avoid lifting the head, especially when handling acidic, alkaline, toxic media, etc., as it is very unsafe.

Do not invert the Cast Iron Gate valve made in China (i.e. with the handwheel facing downwards), otherwise the medium will remain in the valve cover space for a long time, which can easily corrode the valve stem, and certain process requirements are contraindicated. Simultaneously replacing the packing is also extremely inconvenient. Do not install the rising stem gate valve underground, otherwise the exposed valve stem will be corroded by moisture.

When installing a lift check valve, ensure that the valve disc is vertical for flexible lifting. When installing a swing check valve, ensure that the valve disc pin is level for flexible swing. The pressure reducing valve should be installed upright on a horizontal pipeline and should not tilt in any direction.

Before installation:

① Carefully check Flanged Ductile Soft Seated Gate Valve whether the models and specifications of all valves meet the design requirements. (According to the valve model and factory manual, check whether the valve can be used under the specified conditions, and conduct water or air pressure tests if necessary.)

② In addition, it is necessary to check whether the packing is intact, whether the gland bolts have sufficient adjustment allowance, whether the valve stem and valve disc are well matched, and whether there is any jamming or tilting. The sealing surface of the valve disc must be tightly closed. For valves with threaded connections, the quality of the threads should be checked. Unqualified valves cannot be installed and should be stacked or marked separately

③ Remove debris inside the CI gate valve manufacture.

Installation process:

① When lifting the valve, do not tie the rope to the handwheel or valve stem to avoid damaging these components. The rope should be tied to the flange.

② The pipeline connected to the valve must be cleaned.

③ Compressed air can be used to blow away impurities such as iron oxide chips, mud, sand, welding slag, etc. These debris not only easily scratch the sealing surface of the valve, but also large particles of debris (such as welding slag) can block small valves, leading to valve failure.

④ When installing threaded valves, the sealing packing (linen with aluminum oil or PTFE tape) should be wrapped around the pipe threads and should not enter the interior of the valve to avoid accumulation inside the valve and affecting the flow of the medium.

⑤ When installing flange valves, pay attention to tightening the bolts symmetrically and evenly. The valve flange and pipeline flange must be parallel and have a reasonable gap to prevent the valve from generating excessive pressure or even cracking. Pay special attention to brittle materials and valves with low strength. Valves that need to be welded to pipelines should be spot welded first, and then the closure should be fully opened before welding.
