Pressure Gauges Used with Valve Sandwich Regulators

Product Overview

The Automatic Valve Pressure Gauges are visual pressure monitoring instruments designed for use in conjunction with the Automatic Valve Sandwich Pressure Regulators. When a sandwich regulator is installed between a directional control valve and its sub-base or manifold to provide independent pressure regulation at a single valve station, a local pressure gauge allows the technician to visually confirm the set point and monitor system pressure without requiring a separate test port or instrumentation manifold.

Model A5655-160 is the pressure gauge offered for this series, featuring a dual-scale face displaying pressure in both PSI (pounds per square inch) and bar, covering the range of 0 to 160 PSI, which encompasses the typical working pressure range of industrial pneumatic directional control valve systems. The dual-scale format eliminates the need for manual unit conversion during commissioning and troubleshooting in plants that operate with mixed metric and imperial measurement standards.

The gauge mounts directly to the sandwich regulator assembly or a ported connection in the regulated circuit, providing an integral visual indicator for the regulated pressure at that specific valve station. This is particularly valuable in multi-station manifold systems where different actuator circuits require different regulated pressures, and the operator or maintenance technician needs to quickly read and confirm each station's set pressure without a pressure gauge panel or remote instrumentation.

For OEM machine builders who specify the sandwich regulators as part of their actuator speed and force control architecture, pairing each regulator with an A5655-160 pressure gauge provides the end user with a straightforward visual reference for field verification and adjustment of regulated pressure at each station.

Frequently Asked Questions (FAQ)

Q: What regulator is the series gauge designed to work with?

A: The Series pressure gauges are designed for use with the Automatic Valve Single and Double Valve Sandwich Pressure Regulators. The gauge connects to the regulated outlet port of the sandwich regulator to display the regulated pressure at that valve station.

Q: What pressure range does the A5655-160 gauge cover?

A: The A5655-160 gauge has a full-scale range of 0 to 160 PSI, with a corresponding bar scale. This range covers standard industrial compressed air operating pressures from low-pressure pilot circuits up to the maximum working pressure of most pneumatic valve and actuator systems.

Q: Does the gauge display both PSI and bar simultaneously?

A: Yes. The A5655-160 gauge face includes dual scales showing PSI and bar simultaneously, allowing personnel using either unit system to read the pressure directly without conversion.

Q: Is the gauge a direct-reading instrument or does it require power?

A: The A5655-160 is a mechanical Bourdon tube or diaphragm-type pressure gauge that operates without electrical power. It provides a direct visual reading of the pneumatic pressure at the gauge connection port.

Q: How does the pressure gauge connect to the sandwich regulator?

Q: Does the gauge require calibration on a schedule?

A: Industrial pressure gauges are generally replaced rather than recalibrated when accuracy is in question. If the gauge is used in a regulated measurement or documentation program, follow your facility's calibration schedule. For general visual indication duty, inspect the gauge face annually and replace if the pointer shows erratic behavior or the gauge face is damaged.

Installation & Maintenance Guidelines

• Depressurize and lockout/tagout the pneumatic system before installing or replacing the pressure gauge on the sandwich regulator.
• Verify that the gauge connection thread matches the regulator port specification before installation. Use appropriate thread sealant or PTFE tape on the gauge threads.
• Apply thread sealant to the gauge threads, avoiding the first thread to prevent sealant from entering the pressure port.
• Thread the gauge into the regulator port by hand to verify engagement, then tighten with a wrench. Do not over-tighten, as this can damage the gauge case or regulator port.
• Orient the gauge face for maximum readability from the primary operator or maintenance access direction.
• Restore system pressure and verify the gauge reads within the expected pressure range for the regulator set point. A zero reading with pressure applied indicates a blocked connection or failed gauge.
• Protect the gauge from direct mechanical impact and high-vibration installation locations. Install a glycerine-filled gauge or pulsation dampener if the gauge will be subject to pressure pulsations that cause needle flutter.
• Inspect the gauge face and needle annually for readability and correct zero indication with system pressure isolated.
