metal parts such as pads, springs, pins, and levers are purposely
excluded. These pieces can break loose and damage equipment. Remember,
half of all internal parts are on the clean side of your duplexed
system with nothing to stop them in the event of a failure. This
cannot happen with Nugent
Zero Leakage Transfer Valves.
Stainless
steel valve plugs or stainless steel balls are specified in API
614, 3rd edition. Nugent Zero Leakage Transfer Valves
comply with the speculation in total. Their API transfer valves
may include carbon steel and bronze internal parts, thereby violating
the intent of the specification. This is not so with Nugent
Zero Leakage Transfer Valves.

Transferring
flow from one system to another is easy with Nugent
Zero Leakage Transfer Valves:
- Open
valve on equalizing line (provided) to fill and equalize pressure
in both systems.
- Rotate
handle to redirect flow.
- Close
valve on equalizing line.
Other
valve suppliers force you to unscrew locking mechanisms to release
pads or tapered plugs before making the transfer. These short
cuts in the field lead to permanently damaged valves resulting
in leaks that become an environmental hazard, or worse, a health
risk to personnel. These potential liabilities do not exist with
Nugent
Zero Leakage Transfer Valves.
Valve
shoes or pads can restrict flow while passing over the inlet and
outlet ports. This can cause a temporary pressure drop resulting
in equipment shutdown. This does not happen with Nugent
Zero Leakage Transfer Valves.
Maintenance,
if required, is easy. Simply remove the retaining ring at the
top of the valve body and lift the rotor out via a standard threaded
eyebolt provided as part of our complete Seal Kit. Slip the new
seals into place, lubricate the rotor, and gently tap the rotor
back into place. Nugent Zero Leakage
Transfer Valves do not require any special tools or complex
maintenance instructions.
