Two-position two-way direct pull diaphragm solenoid valve

　　Zero pressure start normally open / normally closed

　　2W (31) / 2W12 / 2W21 brass/stainless steel

　　The direct-pull diaphragm solenoid valve opens and closes the valve port by lifting the diaphragm by electromagnetic suction under low pressure or no pressure. Under a certain pressure, first opens the pilot hole on the diaphragm to cause the pressure difference between the upper and lower diaphragms to open and close the valve. mouth. Therefore, this type of solenoid valve is required under no pressure or low pressure conditions. If the fluid has been working at more than 0.1MPA, the YCD21 type is more economical.

　　Applicable fluid Fluid temperature
