Product Description

Q347H/Y turbo fixed high-pressure hard seal ball valve for long-distance pipeline and general industrial pipeline, its safety, resistance to harsh environments, etc. have been specially considered in the design, applicable to a variety of corrosive and non-corrosive media. It is compared with the floating ball valves, when working in the pipeline fluid pressure in front of the ball on the force generated by all transferred to the upper and lower bearings, the ball will not move, the valve sealing by the spring and the media pressure to promote the valve seat to achieve, and thus the valve seat will not withstand excessive pressure, so the fixed ball valve seat deformation is small, the operating torque is light, the sealing performance is reliable, and long service life. Especially suitable for high pressure, large diameter occasions. Design, manufacture and inspection are in accordance with the U.S. ASME and API standards, the appearance of the design of exquisite use of good results. Manual turbine, flange connection, fixed ball, valve body carbon steel or stainless steel, internal PTFE or alloy material seat, using temperature -196 ℃ +550 ℃ according to the sealing material selected for the medium: natural gas, water vapour, oil, acids, alkalis, and other types of media, the pressure level of 150LB ~ 1500LB. Widely used in natural gas pipeline, petrochemical water supply network and other industrial areas. and other industrial fields.
Scope of application.

Widely used in food, medicine, petroleum, chemical, natural gas, iron and steel, environmental protection, paper and other pipeline media cut off or flow.
Product features.

1、The valve seat adopts spring structure, which pushes the seat to the ball to ensure good low-pressure sealing performance.

2、Fixed ball valve valve before the valve, after the valve seat can be sealed, that is, the so-called two-way sealing characteristics, the use of self-contained discharge valve, the valve body cavity can be discharged to the outside.

3、The pivot adopts anti-blowout protection structure and low friction coefficient bearing. With excellent performance, high reliability and wide range of applications

Ball valve installation precautions.

1. Installation work must be careful, do not hit the valve.

2. Before installation, the ball valve should be a check, check the specifications, identify any damage, especially for the valve stem. Also rotate a few times to see if it is skewed, because the transport process, the most likely to hit the crooked valve stem. Also remove the debris in the valve.

3. ball valve lifting, the rope should not be tied to the handwheel or valve stem, so as not to damage these parts, should be tied to the valve body.

4. For the pipeline connected to the ball valve, it must be cleaned. Compressed air can be used to blow away iron oxide chips, mud and sand, welding slag and other debris. These debris, not only easy to bruise the sealing surface of the ball valve, which large particles of debris (such as weld slag), but also blocked small valves, so that it fails.

5. Installation should leave the valve handle rotating position. 6. Ball valves can not be used as throttling. 7. Ball valves with transmission mechanism should be installed upright.
