The high pressure ball valves helps in the provision of an along or digital control of hot water, chilled water which contain about 50% glycol. Each of the unit comprises of a linkage assembly and actuator which is attached to the body of the valve and prevent leakage. The design of the port is to restrict high flow and sustain the pressure.
The size of the valve can range from 0.5 to 3 inches and a valve rating of 6,000 10,000 PSIG for two ways. These low profiles with compact design can be installed easily in a tight and restricted area, terminal reheat coils, fan coils as well as larger air handlers.
This valve makes use of a floating ball in controlling the flow. The valve is opened when the ball’s hole is in line with the flow and it will be closed when it is pivoted at an angle of 90-degrees with the aid of valve handle. The ball valves are durable and help in the retention of its standard after many cycles.
The working pressure of the hydraulic ball is up to 700 Bar and also varies in sizes. Steel and stainless steel materials are used to manufacture these balls. The connections which are common for high ball pressure valves are the compression or threaded type.
