Product Description:
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.
Product Features:
Available in two versions, mounted directly to actuators with NAMUR interface per VDI/VDE 3845 or threaded to mount on the pipe
Valve body in Aluminum, Brass, or Stainless steel 316L
Exhaust ports are pipeable, providing better protection against harsh environments
DIN, watertight, and explosion-proof solenoids are available for use in mission-critical and hazardous areas
Low-power constructions are ideal for remote and alternative power locations
Integral breather block vents to spring side of the actuator to exhaust, preventing corrosion
Single- and dual-solenoid constructions are available that mount in any position
Global Ex approvals; ATEX, IEC EX, NEPSI, CUTR, KOSHA, UL, CSA, InMetro
All ports of NAMUR on the same side for a better water , DUST protection
Available will all Explosion proof solenoids: Ex d, Ex mb, Ex ia/Ib, Ex e mb, NEMA
Available in an arctic version, suitable for use in temperatures as low as -60°C
Compact spool valve convertible from 3/2 to 5/2 with a single flow plate design (551 Series only)

Details
|
|
Valve Actuation
|
Employing a solenoid - air pilot mechanism, this valve actuation method ensures reliable and efficient operation, providing precise control over the valve's opening and closing actions.
|
|
Body Material
|
Available in high - quality brass, corrosion - resistant stainless steel, and lightweight yet durable aluminum. Each material option is carefully selected to meet different application requirements and environmental conditions.
|
|
Media
|
Designed to handle air and inert gases with ease. The valve's construction and sealing materials are compatible with these media, ensuring stable and safe operation.
|
|
Pipe / Port Size
|
Features a standard 1/4" size, which is suitable for a wide range of pipeline systems and can be easily integrated into existing setups.
|
|
Port Type
|
Equipped with G ISO 228/1 - G BSPP and NPTF port types. These common port types offer flexibility in connection, allowing for seamless connection with various pipes and fittings.
|
|
Function
|
Offers multiple functions: 3 - way - 3/2 normally closed for applications where a default closed - state is required; 4 - way - 5/2 for basic directional control; 4 - way - 5/3 - closed center for systems that need to hold the actuator in a neutral position; and 4 - way - 5/3 - open center for applications requiring continuous flow when the valve is in the neutral position.
|
|
Flow
|
The flow rate ranges from 0.5 cv to 1.0 cv and from 0.43 to 0.86 kv, providing sufficient flow capacity for different industrial processes.
|
|
Voltage
|
Compatible with a wide variety of voltages: 24 ac, 110 ac, 120 ac, 220 ac, 480 ac, 6 dc, 12 dc, 24 dc, 120 dc, 240 dc, with a frequency of 50/60 Hz. This wide voltage range makes it adaptable to different power supplies around the world.
|
|
Max Differential / Max Operating Pressure
|
Can operate under pressure conditions ranging from vacuum to 150 psig, making it suitable for applications with different pressure requirements, from low - pressure to relatively high - pressure systems.
|
|
Operating Environment
|
Capable of functioning in diverse operating environments, including corrosive, hazardous, indoor, and outdoor settings. Its robust design and high - quality materials ensure reliable performance even in harsh conditions.
|
|
Standards / Regulations
|
Complies with numerous international standards and regulations such as ATEX Zone 1 - 21, ATEX Zone 2 - 22, Class I Div 1, Class II Div 1, SIL, Type 1, Type 2, Type 3, Type 3S, Type 4, Type 4X, Type 6, Type 6P, Type 7, Type 9. This compliance ensures safety and quality in various industrial applications.
|
|
Temperature
|
Operates within a temperature range of - 60 °C to 80 °C, making it suitable for applications in both extremely cold and relatively high - temperature environments.
