800 Series Hydraulic Control Valves hydraulic control valves general definition Armaş 800 series automatic hydraulic control valves are designed in the “Y” body model type so as to show maximum resistance to cavitation under minimum head loss in high flow rates. Armaş 800 series automatic hydraulic control valves are double-chamber diaphragm actuated and disc closed type. Valve has a standard double control chamber. However, if required, it maybe used as a single control valve without using an extra control chamber. In addition, if required, the valve operates easily controlledly even in...

Using With Single/Double Chamber Actuator Armaş 800 series automatic hydraulic control valves are designed with double-chamber actuator as a standard. Valve can be easily used with single or double-chamber actuator without need for any additional parts. Using with single chamber actuator When using the valve with single-chamber actuator, the plugs under the middle bonnet are removed and a plug is in started into the middle bonnet inlet port and thus, the valve actuator is made with single chamber. In such a case, the pressures to be compared are P1, P2, P3. Using With Single Chamber...

Valve Impact Pressures and Impact Areas. P1 : Upstream Pressure spring A : Disc Impact Area working principles Armaj 800 series automatic hydraulic control valves are designed with doublechamber actuator as a standard. Valve can be easily used with single or doublechamber actuator without need for any additional parts. The control valve ensure that the valve closes hermetically with the valve disc's sitting on the body bush by means ofthe force imposed by the inlet pressure on the diaphragm in the actuator by the pilot valve. When examining the forces on the valve with the aid of impact...

A port A port ensures that the valve operates more sensitively, more smoothly and more silently for flow and pressure regulation and prevents vibration and provides high pressure decrease compared to flat disc. Suggested Use Applications •Pressure reducing valves •Pressure sustaining valves •Deep well pump control valves •Float valves •High pressure reducing and pressure sustaining applications. Non-Suggested Use Applications • Booster Pump Control Valves • Applications that require minimum head loss. • In a condition to have low pressure difference between upstream-downstream. installation...

hydraulic performance cavitation Cavitation occurs in hydraulic control valves when they are not used under proper pressure values. When fluid passes through the closing area of the hydraulic valve, its value will increase due to extreme choking and its static pressure will drop under the evaporation pressure of the fluid. The fluid evaporates and steam bubbles occur in the fluid. Such steam bubbles explode in the outlet side of the valve under the downstream pressure. Such sudden expositions produce intensive shock waves and temperature increases. Extreme reduction in the valve causes...

control valve 3- way selector valve Ball Valve In-line Finger Filter Plug description Armaş“M” model valve is the hydraulic control valve operated by line pressure and designed to ensure opening/closing process by means of 3-way selector valve. Minimum opening pressure of valve is 0.5 bar. Thanks to its flexible diaphragm, stem bedded rigidly and stainless steel spring, it makes easy and fast control process in high pressure applications and is closed as full tightness without causing surge. It may be used in different applications by adding different pilot valves on its main body....

adjustment •Select adjustment position by means of 3-way selector valve indicated with "a"on main valve. •Valve is open in "Open"position and closed in"Close"position. maintenance •System operating conditions that effect on the valve should be checked periodically to determent the required preventative maintenance schedule. •Check finger filter in valve upstream according to water quality. •Drain water within actuator of valve not used in winter.
