British Spirax Sarco Ball Valve Spirax Sarco
Ball Valve
Introduction:
Three-stage ball valve
, as a isolation valve, cannot be used as a control valve. Suitable for steam and other industrial fluids from vacuum to higher temperatures and pressures.
Ball Valve
Correct installation, debugging, and maintenance by professional and qualified personnel are the only guarantees for the safe operation of this valve. During installation, the installation guidelines and safety guidelines for pipelines and factory buildings must be followed, the correct use of tools and the necessary safety equipment must be equipped.
Products are designed for use with Pressure Equipment Directive
class fluids, including steam, air and water
Condensate. If used for other fluids, please consult
Dankuang Valve
.
Ensure that the material of the product is suitable for the working conditions, and the maximum
and minimum pressure and temperature of the system are within the design range of the product. If the maximum working range of the product is lower than the working conditions of the system, or the failure of the product will cause overpressure and temperature, please install a safety device to deal with the danger.

Note: Please read the safety information before installation
Although the valve is structurally sound, stretching caused by poor line alignment and
or incorrect line length can adversely affect the valve. , must be avoided. Pay special attention to correct pipe diameter alignment to ensure that the pipe and valve are on the same axis.
The valve is used in on/off
applications and can be manually operated.
The valve should be installed with sufficient distance to facilitate operation and maintenance.
Before installing the valve, make sure that the diameter, pressure level, material, connection method, etc. are consistent with the application.
Before installation, the ball valve must be cleared of impurities accumulated during storage and must be kept clean during installation, as impurities will damage the valve seal and operating mechanism.
In order to reduce the wear of the valve seat by rough particles, a filter should be installed upstream of the ball valve.
Make sure the handle is in the proper position when installing. The ideal position is with the valve stem in a vertical position. When used with gases, ball valves can be installed in any position.
