MOUNTING, ADJUSTMENT & ASSEMBLY INSTRUCTIONS:

Mounting – Valve can be mounted in any orientation. Valve must be mounted on a flat surface. Special attention should
be paid to not bend or twist the casting when mounting. Doing so may cause the valve to fail.
 Relief Adjustment – Relief setting is factory preset to 1500 psi, unless otherwise noted within model code. Relief valve
can be set anywhere within the range of 500 psi to 3000psi.
To adjust relief pressure: First, remove the round plug above the outlet port with an Allen wrench (0.125”). You
will then have access to the relief set screw. Turning this screw with a 5/32 Allen wrench clockwise 1 turn will
increase pressure approximately 600psi.
 Handle Assembly – To install handle, place the ball end of the handle in the spool and then join handle and the retainer
using the supplied pin
.
 Regardless of handle style, the handle retainer will be installed on valve from factory. Unless specified, the clevis’s
placement is defaulted so the handle points up when the valve is placed on a flat surface. To change this, prior to
handle installation, the screws holding the retainer/clevis must be removed and the clevis can then be rotated 180º
around the spool.
FREQUENTLY ASKED QUESTIONS:
Q: Can I plumb another valve downstream from this valve, using the outlet of this valve?
A: No. The outlet of this valve should be plumbed back to tank.
Q: Can I adjust max flow from my valve? (Ex. Can I go from a 0-15 valve to a 0-45 easily?)
A: This can only be accomplished by switching out to new spool capable of larger flow.
Q: What kits are available for this valve?
A: There is a replacement seal kit (Part #: DCF-K), and replacement relief kit (Part #: DCF-CART-N) 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.
Q: Can I paint the valve?
A: Painting valves is acceptable as long as the following precautions are taken:
1- All ports must be plugged
2- Spool must be masked or taped off completely.
Any paint on the spool will cause leakage when it chips off. Warranty is void if any valve is returned with paint on
the spool.
GENERAL INFORMATION:
Pipe Thread Sealant - Warranty is void when Teflon tape is used to seal pipe threads. This is because Teflon tape is a
friction reducing agent which allows customers to over-torque fittings. We recommend using a sealant that does not include
friction reducing agents i.e. Lead Plate.
