Type N_Moore
Standard VARIVENT® shut off valve
Type N fitted with control cone and
Moore Positioner
Fitted with a pneumatic Moore positioner mounted to a Delrin base, this
valve provides an economic alternative to the Type A or Type S Control
Valves.
Easy to calibrate and in normally open or closed positions, standard
VARIVENT actuators can be utilized for product pressures up to 116 psi.g.

Type N/16
Standard VARIVENT® shut off valve
Type N fitted with control cone and 2
position stop.
Besides closed and fully open, the valve can be
pneumatically driven to two partially open
positions.
Fully adjustable, the limit stops are mechanical
providing precise and repeatable positioning.
Proximity switches can be fitted to the lantern
Typically used for coarse and fine
flow adjustment for dosing
applications

Actuators
Type A
Max product pressures different for
normally open or normally closed
valves.
Type S
Max product pressures different for
normally open or normally closed
valves.
MPP can be increased by adding
springs from 3 to 6.
From OD 2.1/2” valve up, MPP can
also be increased by selecting larger
(MFIII-30) actuator.
Type N/16 and N_Moore
Select Max Product Pressure from
standard actuator charts.
Note that 2 position stop type change
with change in actuator
