NORMALLY OPEN OR NORMALLY CLOSED OPERATION
GENERAL SERVICE - 3/8I, 1/2I OR 3/4I NPT

DESCRIPTION

Series F210 valves are 2-way normally open or normally
closed air operated valves. Valves may be provided with an
instrument air operator for a 3-30 psi signal range or with
a fluidic/logic interface air operator for a 1.5-5 psi signal
range. Series F210 valves are of rugged brass, stainless or
steel construction.

OPERATION

Normally Open: Valve is open when operator is
de-pressurized; closed when pressurized.
Normally Closed: Valve is closed when operator is
de-pressurized; open when pressurized.
Note: No minimum operating pressure differential
required.
Manual Operator
Normally Open Construction Only

operator (close the valve), press stem inward or rotate stem
locknut clockwise until it stops. Valve will be in the same
position as when the operator is pressurized. To disengage
manual operator (open the valve), release stem or rotate
stem locknut counterclockwise until it stops.
CAUTION: For valve to be operated by auxiliary
pressure, manual operator stem locknut must be fully
rotated counterclockwise.

INSTALLATION

Check nameplate for correct catalog number, pressure
(main and auxiliary) and service. Never apply incompatible
fluids or exceed pressure rating of the valve. Installation and
valve maintenance to be performed by qualified personnel.

Air Operator Specifications

S Instrument air operator signal pressure range is 3-30
psi.
S Fluidic/Logic interface air operator signal pressure
range is 1.5-5 psi.

Future Service Considerations

Provision should be made for performing seat leakage,
external leakage, and operational tests on the valve with a
nonhazardous, noncombustible fluid after disassembly and
reassembly.

Temperature Limitations

S Normal ambient temperature range is 32_F (0_ C) to
125_F (52_ C).
S Maximum fluid temperature 180_F (82_C) for
instrument air operator (3-30 psi range).
S Maximum fluid temperature 150_F (65_C) for low
pressure air operator (1.5 - 5 psi range).

Positioning

This valve is designed to perform properly when mounted in
any position. However, for optimum life and performance,
the operator should be mounted vertically and upright to
reduce the possibility of foreign matter accumulating in the
air operator area.

Mounting

For mounting bracket (optional feature) dimensions, refer
to Figure 1.

Piping

Connect piping or tubing to valve according to markings on
valve body. Apply pipe compound sparingly to male pipe
threads only. If applied to valve threads, the compound may
enter the valve and cause operational difficulty. Avoid pipe
strain by properly supporting and aligning piping. When
tightening the pipe, do not use valve or operator as a lever.
Locate wrenches applied to valve body or piping as close as
possible to connection point.
