However, the direct acting type has no such strict requirement. The pilot-operated solenoid valve has a relatively high requirement to the purity of the flowing medium. 5 YRS 4. Order) CN Yueqing Rightheight Technology Co., Ltd. Normally closed (power to open) with coil & DIN plug. Electric Valve Normally Closed 2/2 Way Brass DC 12V 24V AC 220V Electric Solenoid Valve For Water Normally Closed Direct Acting Electric Solenoid Valve 5.00-20.00/ Piece 10.0 Pieces (Min. If voltage is other than 120, please advise. The power and consumption of the directly operated solenoid valve are higher than that of the pilot-operated type. 304 SS general purpose solenoid valve for compressed air or water. For valves, coils, or kits not listed, please provide the rebuild kit number and valve catalog number. Generally, the CV value can reach 3 or above. The flow capacity of the pilot-operated solenoid valve is bigger than that of the directly operated type. If there is an electric pump on the tank locate the switch in a locked. However, as to the direct acting solenoid valve, the main solenoid opens directly. 00 Search for: Sort by Default Order The use of a barrel lock and end cap is an. This is a micro pressure valve (pressure), suitable for 0.02-0.8MPA water pressure, please choose according to your actual needs. When the pilot-operated solenoid valve is energized, the small valve opens at the first and the main valve opens later. This valve is a normally closed solenoid valve, that is, it is energized to turn on (water), and the power is off (water cut). Instead, the directly operated solenoid valve is opened with its main valve directly. If it is only occasionally closed, the normally open solenoid valve should be selected. Because the small valve opens in the first and the main valve opens later when the pilot-operated solenoid valve is supplied with power. The characteristic of the normally open solenoid valve is that the valve body is closed when the coil is energized, the valve body is opened after the coil is powered off, and the solenoid valve in the pipeline is opened for a long time. It is mostly used for the occasion of fast connection and disconnection. The starting speed of the direct acting solenoid valve is quicker than that of the directly operated type. The pilot-operated solenoid valve has a higher tolerance of liquid pressure than the direct acting solenoid valve. Tips: Differences between pilot-operated and direct acting solenoid valve (body length unit = mm, port size unit = inch) Pneumatic solenoid valve, 2-position 3-port, normally closed, single solenoid, is used to handle the flow of air with long service life and high reliability under the working voltage of 12V DC, 24V DC, 110V AC or 220V AC, and widely used in the industrial fields like chemical, petroleum, pharmaceutical, automotive, light industry, food, mineral processing, electroplating, metallurgy, textiles etc.
