Electro-hydraulic diaphragm valve Features: 1, stable and reliable, the service life of more than 10 million times. 2, the opening and closing speed is adjustable to eliminate: "water hammer." 3, automatic and manual control, avoid loading the bypass circuit. 4, horizontally. Vertical mounting. A wide range of applications. 5, open and close flexible. A simple structure. Easy maintenance. 6, the power AC220V. DC24V optional. 7, can be used for natural gas, liquefied petroleum gas, gas, chemical and other industries. 8, by the controller, stepless opening and closing, to achieve constant current, fill volume. 1, the installation of electro-hydraulic valve, ensure the correct flow direction, flow mark on the body. The new pipeline is installed, when flushing the pipeline, electro-hydraulic valve must first be removed, so as not to slag and debris stuck in the valve body, causing electro-hydraulic valve closed lax. 2, the dynamic viscosity of the electro-hydraulic valve working medium ≤40 cps; easy to use junction wax media. 3, after receipt of the equipment, you should immediately check the packaging to see what damage during shipment. Carefully move the device from the box. Check for damaged or missing parts. Check the packing list is consistent with the physical, and order type, size, parameters are consistent. 4, electrical installation, first open the junction box, the middle terminal block as shown: two kinds of wiring method ① normally open solenoid valve coil, a thread pick a column; normally closed solenoid valve coil, a thread connection c column; the other will often open, normally closed solenoid valve coils two thread and then access b column. If you use a 24V DC power supply, A pillar, C pillar positive power supply, B pillar negative one. If you use the AC 220V power supply, A pillar, C pillar connected FireWire, B pillar the zero line. ② If the controller can not control the second set of electromagnetic coils can be a, c and b, respectively, followed by the access controller output. Finally tightened the compression nut cover junction box. For more information, see: www.ylfmc.com/shgnvalve-Products-1898204
