[Features]
· Prevents vibrations to the shaft sliding part, increasing the lifespan of rubber parts. It also helps improve the valve sealing performance.
· Completely stops the leakage of coolant fluid. The scraper effect provides double the safety performance.
· The sealing material can also be selected (NBR, FKM).
· Includes a function for checking whether the valve is open or closed. Mountable on either side (SGC2/3/4 only).
· Prevents the loss of grease, increasing its service life.
· External pilot solenoid type and air operated type.
· Series: SGC200/SGC300SGC400.
· Valve type: N.C./N.O.
