Product Description:
ASCO General Service Valves control the flow of neutral gases. They are known for their long life and fast response time.
???ASCO General Services Valves are available in multiple mounting configurations.
The solenoid is an electromagnetic part of a valve, comprised of a coil, core tube, core and enclosure.
ASCO offers the world’s largest selection of 2-way, 3-way and 4-way solenoid valves, designed to handle the most demanding fluid control applications.
ASCO's 2-Way solenoid valves have one inlet and one outlet, and are used to permit and shut off fluid flow.
The two types of operations are Normally Closed (NC) and Normally Open (NO).
Two types of constructions apply to 2-way solenoid valves, which are direct acting and internally piloted.
With Direct acting constructions, the solenoid is energised, the core directly opens the orifice of a Normally Closed valve or closes the orifice in a Normally Open Valve. The valve will operate at pressures from 0 bar to its rated maximum.
Internally piloted constructions use line pressure to assist operation. When the coil is de-energised (on a Normally Closed Valve), the pilot orifice is closed and line pressure is applied to the top of the piston or diaphragm through the bleed orifice, closing the valve.
ASCO 3-Way Solenoid Valves have three pipe connections and two orifices. When one orifice is open, the other is closed and vice versa. They are commonly used to alternately apply pressure to an exhaust pressure from a valve actuator or a single acting cylinder. These valves can be normally closed, normally open or universal.
ASCO 4-Way Solenoid Valves have four or five pipe connections, commonly called ports. One pressure inlet, two cylinder ports providing pressure to the double acting cylinder or actuator and one or two outlets to exhaust pressure from the cylinders. They have three types of construction, single solenoid, dual solenoid or single air operator.
