5. Installation Procedures
Install the valve so that the flow is in the proper direction.
The "INLET" and "OUTLET" connections are indicated in
the general arrangement drawing in Appendix A. The
connections offered include the following:
− ¾” MP – those connections are suitable for
Autoclave Engineers or Butech fittings.
−
1” MP – those connections are suitable for
Autoclave Engineers or Butech fittings.
−
Grayloc Hub 1GR5 (Short)
−
Grayloc Hub 1GR7 (Long)
The "VENT" connection is not under pressure and will see
fluid only if the piston seal is leaking. This connection is
1/4" NPT and may be routed to a drain or atmospheric
container if desired. The "VENT" must remain free and
unrestricted, and should be visible.
The supply pump pulsations must be adequately
dampened with a pulsation dampener to avoid setting up
a resonant vibration in the SkoFlo valve.
6. Start-up Procedures
1. Open the supply isolation valve to the back-
pressure regulator slowly.
2. Turn the pressure adjustment handle clockwise
until you are at the desired pressure. Always start
at a pressure below the set pressure and increase
to the desired setting.
3. The BPR is now set and further adjustments aren't
required. Tighten the lock nut on the handle to
avoid inadvertent changes to the adjustment.
7. Operation Notes and Warnings
The SkoFlo Back Pressure Regulator has hard seats and is
not designed to provide complete "bubble-tight" shut off.
If tight shutoff is required, separate isolation valves should
be used for shutting off the flow. Overtightening the
handle will not further reduce flow. If the back pressure
does not increase when turning the handle clockwise. See
"Trouble Shooting Improper Valve Performance".
! WARNING
WEAR PROPER PERSONAL PROTECTIVE EQUIPMENT (PPE)
AS REQUIRED BY SITE SAFETY PERSONNEL WHEN
INSTALLING AND TESTING.
MAINTAIN SAFE WORKING DISTANCES AS DETERMINED
BY SITE SAFETY PERSONNEL WHEN TESTING.
CONSULT SKOFLO IF ANY PRODUCT CONCERNS ARISE
DURING HANDLING.
! CAUTION
DO NOT FLOW BACKWARDS THROUGH THE SKOFLO
VALVE. INTERNAL SEALS ARE DESIGNED FOR ONE
DIRECTION ONLY AND COULD POSSIBLY BECOME
DISLODGED.
! CAUTION
DO NOT ADJUST THE VALVE FROM OPEN TO CLOSED
POSITION UNLESS VALVE IS PRESSURIZED TO AVOID
THE POSSIBILITY OF DISLODGING THE STEM SEAL.
! NOTICE
INSTALL A PULSATION DAMPENER BETWEEN THE
PUMP DISCHARGE AND THE SKOFLO BACK PRESSURE
REGULATOR AS REQUIRED TO AVOID POSSIBLE
DAMAGE AND NOISE FROM HARMONIC PULSATIONS.
! NOTICE
INSTALL RELIEF VALVE AND/OR BURST PLATE
UPSTREAM OF THE SKOFLO BACK PRESSURE
REGULATOR AS REQUIRED.
! CAUTION
THE VENT FROM THE SPRING CHAMBER MUST NOT BE
BLOCKED. LEAVE OPEN TO ATMOSPHERE, OR ROUTE TO
A DRAIN COLLECTION POINT AT ATMOSPHERIC
PRESSURE. THIS VENT WILL ONLY HAVE FLUID IN THE
EVENT OF A LEAKING PISTON SEAL.
! NOTICE
WHEN LIFTING THE SKOFLO VALVE, LIFT USING
M12 X 1.75 EYEBOLTS IN SIDE OF BODY. DO
NOT LIFT USING THE HANDLE AS THIS CAN
DAMAGE THE HANDLE.
