Lock Cylinders

• Locking cylinders lock at any desired stroke position.

Speed Controllers w/Pilot Check Valve

5 Port Solenoid Valve w/Double Check

• Combining the double check block with a 3-position exhaust center solenoid valve will enable the cylinder to stop in the middle of maintain its position for long periods of time.
• The combination with a 2-position single/double solenoid valve will prevent the dropping at the cylinder stroke end when the SUP residual pressure is released.
