FREQUENTLY ASKED QUESTIONS cont’d:
Q: Can I plumb another valve downstream from this valve, using the outlet of this valve?
A: You cannot plumb direct to another valve, unless your valve is equipped with
power beyond or has been converted to use power beyond. A valve can be ordered
with power beyond already set up by adding a W to the end of the model code.
 Converting valve to “Power Beyond” – To convert the valve to power
beyond operation, take the TS315 plug from the top port (1) and insert it
into the internal port (2). Next, plumb a #10 SAE fitting from the top
port (1) to the adjoining valve. Lastly, run a line from the #12 SAE
outlet port (3) to the reservoir. (See illustration right )
Q: Can I convert my valve to operate in a “Closed” system?
A: Yes. To have the casting in closed center operation, both the top port (1) and internal port (2) must be plugged. Remove
the TS315 plug from the top port (1) and insert it into the internal port (2). Then plug the top port (1) with any std. SAE plug
(7/8 – 14) or purchase a plug from the factory. Closed center blocks “Pump” only, the condition of ports A and B depend on
the spool type. (See illustration above right)
Q: What kits are available for this valve?
A: There is a replacement seal kit (Part #: TS-K), and replacement relief kit (Part #: 34R15) for this valve. There are also a
number of different kits available for this valve depending on the spool action, and handle option the valve is equipped with.
Please contact factory for specific kit numbers relating to different spool actions, and handle options.
