1The manual part of q46f soft seal four-way ball valve can be made of steel plate or cast by stainless steel. The handle is equipped with a limit structure to set the limit at the opening and closing positions of the valve. When the valve is used on the key device, the limit block is provided with a lock hole to lock the switch position to avoid misoperation. The handle is clearly marked with opening and closing.
2. The valve stem of q46f ball valve is forged and modulated by a182f (1Cr13), and the hardness reaches hb220-250. The valve rod is connected with the handle through flat key or spline or square wedge, which has strong universality and is easy to disassemble and assemble. The valve rod is equipped with anti blowing structure.
3. The packing of q46f ball valve adopts braided, flexible graphite sealing ring or tetrafluoroene sealing ring, which makes the valve stem reliable sealing under certain lubrication conditions.
4. According to the requirements, the ball valve can be designed as an anti-static structure, and conductive springs are set between the ball and the valve stem, and between the valve stem and the valve body, so as to avoid the ignition of flammable substances by static electricity and ensure the safety of the system.
5. The seal pairs have various forms. According to different working conditions, soft seal, hard seal, fireproof valve seat and other structures can be selected; floating ball type is below DN 150, and fixed ball form is below DN200.
6. The auxiliary sealing structure can be set at the valve seat of the ball valve, and the grease injection valve can be installed at the valve seat and the valve rod, which can be temporarily sealed in case of emergency, and the valve rod can be lengthened according to the need to be suitable for the place of buried laying.

1. Be careful in installation and construction, and do not hit the valve.
2. Before installation, the ball valve should be inspected to check the specification and model, and identify whether there is damage, especially for the valve stem. Also turn a few times to see if it is skewed, because during transportation, it is easy to bump the stem. Also remove the debris in the valve.
3. When lifting the ball valve, the rope should not be tied to the hand wheel or the valve stem to avoid damage to these parts, but should be tied to the valve body.
4. The pipeline connected to the ball valve must be cleaned. Compressed air can be used to blow away iron oxide chips, mud and sand, welding slag and other impurities. These debris, not only easy to scratch the sealing surface of the ball valve, in which large particles of debris (such as welding slag), but also block the small valve, so that its failure.
5. The position of valve handle rotation should be reserved during installation. 6. The ball valve cannot be used as throttling. 7. The ball valve with transmission mechanism shall be installed vertically.
