In the event you liked this informative article as well as you would like to acquire details with regards to [https://www.shunchengvalve.com/oem-ball-valve/ visit this hyperlink] generously visit our web-site. Invented in the early 1960's by Dr. Harry W. Deutsch, this valve is widely used in the plumbing, heating and air conditioning industry. Many people are familiar with the white or blue valves found on valves for hot water, steam and air conditioners. ABA ball valves are designed to make an air tight seal with a watertight gasket. The design of this valve has been patented, making it one of the few available, to meet the unique design requirements of plumbing and cooling applications.<br><br><br>The air actuated ball valve consists of two halves that are connected by a flexible metallic hose that extends from the lower valve to the upper ball assembly. The hose contains an adjustable air supply pressure cell and a piston. The piston moves up and down, providing hydraulic friction to move the valve up and down along the flexible hose. It is the air supply pressure cell that raises and lowers the ball, which causes the valve to either close or open, based on the air supply pressure.<br><br><br>The air actuated ball valve consists of a single-piece flexible metallic valve assembly and a specially designed valve stem. It can be made of various materials including brass, pewter, copper, stainless steel and other metal alloys. The single-acting component eliminates the need for two pieces or separate actuators for valve operation. This valve design makes it ideal for plumbing applications because the two parts are usually mounted together.<br><br><br>The air actuated ball valve usually has a single control or key valve. When the valve is in a fully open position, the key valve moves up and down if the air source is in supply. When the valve is in a closed position, the key valve remains in the open position. A double acting or two stage valve is used in these types of valves so that the air source pressure can be adjusted to the desired level.<br><br><br>Some of these air actuated ball valves are available as full port and half port units. Full ports are installed in the entire pipe of a system where there are multiple outlets or faucets. Half ports are available in systems where there is only one outlet or faucet. In half port units, the valves are installed in the center of the system where the valve seat is located.<br><br><br>The air actuated ball valve comes in a variety of sizes and designs. These include single stage and dual-stage units. There is also a special type of air actuated ball valve that is referred to as a Paddle valve. In a Paddle valve there is only a single actuator that is used to control the opening and closing of the valve. Most of these valves are used in the food processing industry as they control the amount of hydraulic pressure that is applied to the mechanical process control.<br>' |
