All MOGAS valves operate counter-clockwise to open, clockwise to close.
MOGAS valves are supplied in a variety of operator configurations based
upon customer requirements, and may be operated by
• manual actuation (handlever) • pneumatic actuation
• worm gear actuation (handwheel) • hydraulic actuation
Each of these operator configurations may be installed and tested prior to
shipping, or shipped separately, depending on customer requirements.
Some valves are supplied with a bare stem or stem adaptor kits to
accommodate a variety of manual or actuated operators.
Please note the configuration of each individual valve and proceed with any
necessary operator adaption procedures prior to installing the valve. CLOSE

procedure.
How to Read this Manual
Read Before Installing Valve
Note:
The normal direction of flow is from the higher pressure end
(upstream) to lower pressure end when the valve is closed.
CAUTION!
Ensure key length provides and maintains full
engagement.
THIS WILL AFFECT THE VALVE WARRANTY.
!
PRE-INSTALLATION STORAGE
Valves shall remain stored in their shipping crates
with the lids secured.
INSTALL STEM ADAPTOR
Align stem adaptor 13 so the keyways on stem
adaptor correspond with the keys 06 on stem 05.

These procedures outline the general requirements for storage of MOGAS valves.
TRANSPORT
Valves will be shipped in seaworthy export packed wooden crates that are plastic lined.
Upon arrival at the site, inspect the general condition of the valve (and actuator, if supplied)
for any potential shipping damage.
PRE-INSTALLATION STORAGE
Valves shall remain stored in their shipping crates, or on their pallets, with the lids secured.
For long-term storage, the internal parts of carbon and alloy steel valves should be sprayed
with a rust preventative.
All protective covers and plastic liners should remain in place.
REMOVING VALVE FROM SERVICE
Before the valve is removed from the line, it should be placed in the open position to prevent
further internal damage to valve components.
Once removed, the valve should be placed in a vertical position, or raised at an angle. The
bore of the valve should be either steamed cleaned or power washed to remove slurry and
debris.
The valve should be allowed to drain and dry. A petroleum-based rust inhibitor should be
applied through the bore of the valve immediately after the valve is dry.
Flange protectors need to be secured to each end of the valve to prevent any foreign debris
from entering the valve. It is recommended to place desiccant dryer bags inside the valve
before storage.
The valve should be stored in the vertical position, out of the weather (inside), until repairs
can be made.

PRESSURE END
Preferred Sealing Seat is located
opposite the pressure end (downstream).
Pressure End is indicated on flange in this location.
When valve is in closed position,
higher pressure should be on this side.
Correct Valve Orientation
Identify Preferred Sealing Seat
2-PIECE BODY
Viewed from TOP
For correct installation, you must verify:
Flow Direction – The preferred direction of flow is from the higher pressure end (upstream)
to lower pressure end, when the valve is closed. In certain conditions, proper operation may
require the sealing seat be positioned opposed to the flow direction.
Pressure End – Always marked on the valve prior to leaving the factory.
Preferred Sealing Seat – Located opposite the marked pressure end, in the downstream
position.
The valve must be installed with the marked pressure end positioned toward the higher
pressure when in the closed position.
