Due to WS2H internals being discontinued, when replacing the stack and or piston of a WS2H valve,
YOU MUST purchase a V3630 rebuild kit and
REPLACE THE ENTIRE DRIVE ASSEMBLY FOR PROPER VALVE FUNCTION.
SPECIAL ORDER ITEM - Usually Ships in 4 to 6 Weeks
After switching to this replacement KIT ( V3630 ),
you can then "rebuild" your older WS2H using the WS3 replacement parts the next time.
Note: the WS2H valve was discontinued in 2016,
and that is why Clack has created this replacement KIT
to allow customers to continue to rebuild using the available WS3 parts.
This Rebuild kit includes parts V3093,V3092,V3666-01, and V3238-01
* WARNING: Do NOT lubricate the Stacker assembly. Internal o-rings are silicone, and the tolerance is already "tight".
Adding any lubricant can cause the piston to "bind", and also "pull out" and damage o-rings.
Also, these o-rings are NOT sold separately.
So if you damage the Spacer Stack Assembly, you have to replace the entire Assembly.
