Two-Valve Static Pressure Manifolds |
|
The PM50 combines a primary block valve, a bleed valve, and a secondary shutoff valve into one small unit. With the integral secondary shutoff valve and a bleed valve (not integral), the gauge and transmitter can be removed or bled without requiring additional valving. The PM50 features a threaded inlet and flanged outlet, allowing the transmitter to bolt directly to the manifold.

|
The PM59 is a line-mounted two valve manifold that functions as a shutoff and bleed valve for static pressure instrumentation. The use of the PM59 reduces the number of threaded connections, resulting in fewer potential leak points.

Three-Valve Differential Pressure Manifolds |
Hex produces a complete line of three valve instrument manifolds which combine two block valves and one equalizing valve in a single compact assembly.
- PM45/46: for in-line, thread by thread installations
- PM53: single flanged for mounting to a remotely located differential pressure transmitter
- PM54: double flanged for direct mounting to the orifice flange or for remote transmitter locations.
- PM51: direct mounted compact water

Five-Valve Differential Pressure |
|
The PM75 is designed for remote mounting of differential pressure transmitters. Design includes two isolation valves, one test valve, and two test/purge valves. Manifolds can be mounted via pipe stand or instrument rack. The 1/2" process connection is located on bottom of manifold and instrument connection is located on back.
|
 |
|
The PM76 is similar to the PM75 but is designed for direct mounting to transmitter by unique water design. The compact design eliminates the requirement for additional tubing or piping from manifold to transmitter.

|
Rigid Mount |
|
The PM13 (3-valve) and PM16 (5-valve) mount directly to the pipe stand securing the impulse lines so the transmitter can be installed or removed independently of the piping.

Orifice Block Valves |
|
The PG65 block valve is designed for compact side-by-side mounting on orifice flanges and orifice settings, as well as for use with condensate chambers, mercury traps, and seal traps. The slim design enables side-by-side mounting on 2-1/8" centers without staggering the valves with unequal length nipples as required with other valves. This valve provides two outlet ports for use as impulse line connections, pressure gauge mounting or level gauge mounting.

Needle Valves/Bleed Valves |
| The PN49 is a fully packed needle valve for high pressure and high temperature applications. Produced in a wide variety of inlet and outlet sizes.
For critical services, the PB59 block and bleed valve features a fully packed and backseated block valve along with a fully packed integral bleed valve.
|
 |
|
Gauge/Block Valves |
| Hex Gauge/Block Valves provide three outlet connections to facilitate the mounting of gauges and other static pressure instrumentation in a variety of positions. The design results in a compact installation with minimal leak points.
The PG46 features the backseated OS&Y bolted bonnet, while the PG48 is supplied with backseated screwed bonnet.
The PG47 provides a full port and unrestricted flow, which allows the use of a rod-out tool.
