Directional control of cylinders and actuators starts with a well-built spool valve. The ASCO 55102087 is a Series 551 spool valve with 1/4" ports.
Series 551 is ASCO's range of pneumatic spool valves for directing compressed air to cylinders and actuators. A spool valve shifts an internal spool to connect supply, outlet and exhaust ports, giving clean directional control.
In pneumatic systems, small components decide whether a machine runs smoothly or keeps stopping. A worn or mismatched valve leaks air, slows cylinders and makes fault-finding harder for maintenance teams. Fitting a genuine ASCO part with the right function and connections keeps the circuit predictable, cuts compressed-air waste, which is one of the most expensive utilities in a plant, and makes future replacement a simple like-for-like swap.
Series 551 valves can be banked on ASCO Series 881 supply rails, so the ASCO 55102087 fits neatly into a tidy, modular pneumatic panel.
Need a different rating within the family? Compare the ASCO 55102099 (5/3, lever operated) or the ASCO 55102096 (2-position, lever operated), and keep the same installation approach.

Frequently Asked Questions
What is a spool valve used for?
It directs compressed air to the ports of a cylinder or actuator so it extends, retracts or holds position.
Can the 55102087 be mounted on a supply rail?
Series 551 valves can be banked on ASCO Series 881 supply rails. Confirm the rail size you need for the number of valves.
What port size is the 55102087?
It has 1/4" connections. Check that your fittings match before installation.
Should I choose the 55102087 or another ASCO model?
Start with your supply voltage, port size and required function. The 55102087 has 1/4" ports. If you need 5/3, lever operated, the ASCO 55102099 may suit better. If you need 2-position, lever operated, the ASCO 55102096 may suit better. Contact our team to confirm.
How should I maintain the 55102087?
Supply clean, dry, filtered air, check for audible leaks during routine rounds, and replace the valve or its seals when switching becomes sluggish.
What is the most common mistake when ordering a pneumatic valve?
Choosing the wrong function or port size. Check the circuit diagram and the full part number before ordering.
