The Pneu-Trol gauge isolator valve is designed to prevent surge damage to a gauge in all types of hydraulic circuits. The gauge isolator valve also acts as a snubber to prevent damage to other hydraulic components - hydraulic chatter, pulsation and fluid hammer can cause costly down time of equipment.

Simple to operate - just push to read. Depressing the knob allows fluid to flow around the spool to the gauge. When the spring-loaded knob is released the spool is automatically returned to the closed position, allowing the fluid to drain from the gauge out the tank port.
