diaphragm valve การใช้

• Diaphragm valves can be manual or automated.
• Most automatic irrigation valves are diaphragm valves in which the water above the diaphragm must be discharged for the valve to open.
• Gate, globe, and check valves are usually hard seated while butterfly, ball, plug, and diaphragm valves are usually soft seated.
• A base resistant compound with excellent steam resistance, Ultraz performance far exceeds the baselines of EPDM or PTFE . It is typically used as a membrane material in hygienic diaphragm Valves.
• In the event of electronics or pump failure, there is also usually a secondary bowl attached to the top of receiver bowl, which contains a float and a diaphragm valve.
• In addition to the well known, two way shut off diaphragm valve, other types include : Three way zero deadleg valve, sterile access port, block and bleed, valbow and tank bottom valve.
• Between 1935 and 1938, the company introduced a long list of valve and thermostat products, including automatic spring valves, ball float valves, pressure-controlled valves, diaphragm valves, suction valves, constant-pressure valves, room thermostats and drying filters.
• Diaphragm valves can be controlled by various types of actuators e . g . manual, pneumatic, hydraulic, electric etc . The most common diaphragm valves use pneumatic actuators; in this type of valve, air pressure is applied through a pilot valve into the actuator which in turn raises the diaphragm and opens the valve.
