ITEM NAME:Dn15 1/2 Inch Water Pressure Reducing Regulator Adjustable Thread Water Pre U7B9 Dn15 1/2 Inch Water Pressure Reducing Regulator Adjustable Thread Water Pre U7B9 First,the scope of use:Ball valves are primarily used on pipes to cut, distribute,and change the direction of media flow. In order to extend the life of the ball valve, it should be fully open and fully closed.Second,the main technical parameters of the product:1.Use high-quality copper material and adopt hot forging process.2. The working medium of the ball valve is water,oil and gas.3.Working temperature -10 Celsius less than or equal to t less than or equal to 120 Celsius. 4. The nominal pressures are 2.5MPa, 2.0MPa and 1.6MPa respectively.Third, the installation guide:1. For the ball valve with pipe thread connection, when the screw is installed, the pipe should be perpendicular to the end face of the valve body, and the hexagonal or octagonal part of the same side of the thread should be clamped. The hexagonal or octagonal or other parts of the other end should not be wrenched to avoid Causes the valve body to deform or affect the opening. 2. When the internal thread is connected to the ball valve, the external thread length of the pipe end must be controlled to avoid the pipe end thread being too long. When screwing in, the ball end face of the ball valve is pressed, which causes the valve body to deform and affect the sealing performance. 3. When the ball valve connected with the pipe thread is connected with the thread of the pipe end, the internal thread may be a conical pipe thread or a cylindrical pipe thread, but the external thread must be a conical pipe thread, otherwise the connection may not be tight and leak.4. The indexing circle on the flange ball valve should match the size of the indexing circle on the pipe flange. The center of the pipe at both ends should be perpendicular to the flange surface of the flange ball valve. Otherwise, the valve body will be distorted and deformed.When the ball valve connected with the pipe thread is connected with the thread of the pipe end, the internal thread may be a conical pipe thread or a cylindrical pipe thread, but the external thread must be a conical pipe thread, otherwise the connection may not be tight and leak.4.
