ASCO Valve, Inc. products

The ASCO Series 551, also known as 8551, is a line of 1/4" 3-way and 4-way compact solenoid spool valves that are ideal for controlling air or inert gas in challenging environments. The valves’ unique design combines hard T-seals and flexible O-rings that provide bubble-tight shutoff, dirt resistance, and multi-million cycle reliability. The 551 Series comes in anodized aluminum, brass, and stainless steel bodies with ¼-inch NPT and BSP connections. It is suitable for the harsh conditions found in chemicals, refining, food & beverage applications and life science processing.

The ASCO Series 553, also known as 8553, is a line of 1/2" 3-way and 4-way compact solenoid spool valves that are ideal for controlling air or inert gas in challenging environments. The valves ’ unique design combines hard T-seals and flexible O-rings that provide bubble-tight shutoff, dirt resistance, and multi-million cycle reliability. The 551 Series comes in anodized aluminum, brass, and stainless steel bodies with ½-inch NPT and BSP connections. It is suitable for the harsh conditions found in chemicals, refining, food & beverage applications and life science processing.

With a strong compact body and superior design the Sirai range of general purpose valves are highly versatile and ideally suited to the control of water, air, inert gases, steam and non-aggressive fluids.

SIRAI micro solenoid valves can control a variety of non-aggressive liquid and gaseous fluids. In addition to maintaining an excellent balance between miniaturisation and reliability, the innovative design enables the valves to be easily disassembled for cleaning and maintenance.

In a total isolation (Dry) solenoid valve the fluid comes into contact solely with the valve body and the separation lever / diaphragm. This protects the fluid from contamination and from excessive temperature changes.

Pinch solenoid valves can control any fluids that are compatible with the tubing material, protecting the fluid from all contamination, including temperature changes. These valves are suitable for a wide variety of uses, particularly the control of physiological, medical and food fluids.

The switch is designed so to open a three-pole electric circuit when the pressure in the system rises and to close it when the pressure decreases. Designed for electric boilers of coffee machines as main application. In conformity with EU Directive 2002/95/EC (RoHS Directive).

Wide range of pressure ratings, sizes, and resilient materials provide long service life and low internal leakage. Our most economical, high flow valves for liquid, corrosive, and air/inert gas service. Industrial applications include: car wash, air compressors, pumps, laundry equipment, industrial water control

Internal piloting controls large orifices to provide high flows. Pilot operated. Can be used to pilot large actuators and provide quick closing of large control valves. Resilient seating for tight shutoff. Also available in Low Power, Intrinsically Safe, Voltage Ranging and Zero Minimum constructions.
