Microsoft Yahei Gate Valve Installation Instructions< br/>Structure description and principle of Microsoft Yahei
Microsoft Yahei (
Microsoft Yahei) has small flow resistance. The internal medium channel of the valve body is straight, the medium flows in a straight line, and the flow resistance is small.
Microsoft Yahei (
Microsoft Yahei) requires less effort when opening and closing. It is compared with the stop valve, because no matter it is open or closed, the movement direction of the gate is perpendicular to the direction of medium flow.
Microsoft Yahei (
Microsoft Yahei) gate valve can only be fully opened and fully closed, but cannot be adjusted or throttled. It is currently widely used in water supply systems.

Microsoft Yahei)
Microsoft Yahei uses a corresponding torque wrench or pipe wrench to pull the octagon on the same side of the thread. Just screw the part into the effective length of the thread. Do not overdo it and press the inner section.
Microsoft Yahei screw-in uses polytetraethylene tape or thread sealant for sealing.
Microsoft Yahei (
Microsoft Yahei) handwheel is designed according to the corresponding torque. Do not use an increased strength arm instead to avoid damage to the valve. The valve stem sealing packing is made of polytetraethylene raw material tape. If leakage occurs due to abrasion
Microsoft Yahei can tighten the gland to compress the packing. To replace the packing, the medium pressure needs to be relieved. Ball valves for refrigeration and HVAC systems must use Microsoft Yahei (or above hectare pressure) specifications
Microsoft Yahei valves.
When installing the Microsoft Yahei (
Microsoft Yahei) flange gate valve, you must ensure that the flange planes at both ends of the pipe are parallel to the coaxial axis, the spacing size is appropriate, and the connecting screw holes are corresponding. The deviation should not be too large, otherwise it will affect the Valve installation quality and sealing performance.
