Type 252 Filter
Introduction
Maximum Working Pressure
The Type 252 filter is designed to clean
supply gas or air before it enters the pilot
on a pilot-operated regulator, pneumatic
instrument, or other device that requires
clean gas to operate properly. The extended
length filter has a larger drip chamber to hold
more moisture and debris. Filter materials
comply with the recommendations of the
National Association of Corrosive Engineers
(NACE) MR0175.

Type P594 Filters
Introduction
Maximum Working Pressure
Type P594 filters are designed to remove dirt,
scale, or other solid substances from gas
supply lines to pilots and instruments. They
are constructed entirely of brass with the
exception of the filter element, which is
cellulose. The filter element is readily
accessible and easily cleaned or replaced.

Type 67AFD Filter
Introduction
Maximum Inlet and Outlet Pressures
The Type 67AFD aluminum body filter with
drip pot removes dirt, moisture, and other
particles from air or gas lines. It is commonly
used in pneumatic instruments that do not
require a pressure reducing regulator.
250 psig (17,2 bar)
This filter features two outlet connections,
one 90 degrees and the other 180 degrees from
the inlet connection. The filter comes from
the factory with a pipe plug in the 180 degree
outlet. The plug may be easily changed from
one outlet connection to the other as dictated
by piping requirements.
The filter must be installed with the drain
valve pointing down to provide adequate
drainage. For remote drainage, the drain valve
may be removed and 1/4-inch pipe or tubing
installed in its place.

Y602 Series Vent Assemblies
Introduction
Y602 Series vent assemblies help to prevent
the obstruction of vent openings, allowing
proper air or gas flow. These assemblies are
available in either angle or straight styles.
Both styles provide protection to vent
openings when installed and oriented so that
the opening in the vent assembly faces
downward. Many Y602 Series vents feature a
double-lip moisture deflector to resist water
bridging across the vent opening.

Type N850 Snappy Joe® Transfer Safety Valves
Introduction
Maximum Pressure
The Type N850 transfer safety valve is
designed for in-line installation, usually near a
bulkhead. These valves provide a means of
shutting off the flow of product in the event
of a hose rupture or piping breaks at the
transfer area. In this way large scale loss of
product and discharge to the environment can
be avoided. The valves are manually opened
and can be closed either manually at the
installed location or remotely by cable or air.
A thermal release is also built into the unit.

Type N862 Transfer Safety Shutoff Valve
Introduction
Closing Flow Rates
The Type N862 is designed specifically for
storage vessel protection. Shaped like an
elongated pipe, the valve is available with two
nipple sizes and an extension coupling. The
nipple threads are hardened stainless steel to
hold up under repeated use. The valve is
pneumatically opened and closed through a
standard quick-disconnect coupling. All
moving parts are inside of the valve to
minimize damage from rough handling. The
body and internal parts are of either stainless
steel or plated steel.

Type 111 Needle Valve
Introduction
Maximum Valve Body Pressure
The Type 111 needle valve is a small,
lightweight manual throttling valve typically
used when the application requires a small
port diameter and a large end connection. The
needle valve is operated by uncapping the
bonnet, inserting a key over the recessed valve
stem, and turning the key. After adjustment,
the bonnet is capped to inhibit tampering.
