Q11F Brass Threaded Ball Valve
I. Product Introduction:
Brass threaded ball valves are suitable for chemical, petrochemical, petroleum, paper-making, mining, electric power, liquefied gas, food, pharmaceutical, water supply and drainage, municipal engineering, mechanical equipment matching, electronic industry, urban construction and other fields. This valve has a compact structure, reliable sealing, simple structure, and convenient maintenance. The sealing surface and the spherical core are often in a closed state, which is not easily eroded by the medium, and is easy to operate and maintain. It is especially suitable for media containing fibers, tiny solid particles, etc. Multi-way ball valves can not only flexibly control the convergence, diversion, and flow direction switching of the medium in the pipeline, but also are mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. Among them, the hard-sealed V-shaped ball valve has strong shear force between its V-shaped ball core and the metal valve seat surfaced with hard alloy.
II. Product Parameters:
(1) The price of the ball valve varies according to the caliber, material, and pressure, and the price is not provided for reference!
(2) Connection forms: threaded, flanged, welded, wafer, etc.
(3) Transmission modes: manual, worm gear drive, gear drive, pneumatic, electric, etc.
(4) Caliber range: DN6-DN600; Pressure range: 1.0MPA-64MPA; Temperature range: -100℃-600℃
(5) Materials: carbon steel, stainless steel, alloy steel, chrome-molybdenum steel, low-temperature steel, ductile iron, and other special steels;
III. Product Principle:
It is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. Among them, the hard-sealed V-shaped ball valve has strong shear force between its V-shaped ball core and the metal valve seat surfaced with hard alloy, and is especially suitable for media containing fibers, tiny solid particles, etc. Multi-way ball valves can not only flexibly control the convergence, diversion, and flow direction switching of the medium in the pipeline, but also can close any channel to connect the other two channels. This type of valve should generally be installed horizontally in the pipeline.
IV. Installation:
1. Remove the protective covers on both sides of the flange end, and flush and clean the valve when it is fully open.
2. For the balance valve with actuator, before installation, conduct a complete machine test according to the specified signal (electric or pneumatic) (to prevent the impact of vibration generated during transportation on the performance), and it can be installed online only after passing the test (wiring shall be carried out according to the wiring diagram of the electric actuator).
3. Before preparing to connect with the pipeline, it is necessary to flush and remove the residual impurities in the pipeline (these substances may damage the valve seat and ball core).
4. During installation, please do not use the actuator part of the valve as a lifting point to avoid damaging the actuator and accessories.
5. This type of valve shall be installed in the horizontal or vertical direction of the pipeline.
6. The pipeline near the installation point shall not sag or bear external force. Pipeline supports or supports can be used to eliminate the deviation of the pipeline.
7. After connecting with the pipeline, please cross-lock the flange connecting bolts with the specified torque.
