DIAPHRAGMATIC HYDRAULIC VALVES SERIES AS-A

GEMAK created the design of this series of valve AS-A in order to eliminate the problems, found to the irrigation-water supply and pumping networks. AS-A series valves are hydraulically operated by means of a diaphragm which is located to the interior of the valve. Their regulation does not need any special knowledge. By mounting various pilots or three-way electromagnetic valves on their body, a large range of applications is achieved and all demands for regular and soft operation as well as for total protection of the waterworks are covered. Such as:Anti hammer shock valves Pump controlling valves with automatic stop of the pump's operation. Level-flow control valves Check valves Pressure reducing and sustaining valves Tele-controlled valves used for the automation of the pumping, tanks, irrigation and water supply networks. The ability to control the opening and closing speed from 2 seconds to 180 seconds gives ideal conditions for the operation and the safety of the pumping water supply and irrigation networks. The AS-A series valves consisted of two configurations of construction.1) Y type of single and double chamber2) Angle type of single and double chamberThe valves of the double chamber give the ability for multiple applications and smooth closing and operating (T=2sec-15sec) and therefore the creation of even a small pressure surge caused by the valve itself, is avoided. The valves of the single chamber have a limited margin of applications but they give the same safety and operation conditions as those of the double chamber, when they are used for the regulation of pressure and the immediate relief of pressure.
