Flow Control & Instrumentation
Compressor Package End Devices, Instrumentation, and Valves.
Accurate flow control and reliable instrumentation are critical to safe, efficient natural gas compression operations. A stuck valve or a failed gauge doesn’t just create a maintenance headache — it can trigger a shutdown, a safety event, or an emissions violation. RES Energy Solutions supplies valves, gauges, and instrumentation from the brands that compression and midstream operators trust, with same-day availability on stocked items.

Engineering note: Valve sizing is application-specific — pressure rating, temperature range, connection size, and end type all affect selection. Provide your process conditions and RES Energy Solutions will confirm the right valve specification.
Gauges & Instrumentation
FW Murphy Production Controls
FW Murphy’s gauges and instrumentation products are standard equipment on natural gas compression packages across the industry — simple, robust, and built for field environments where reliability matters more than complexity.
- Pressure gauges for compression and process applications
- Temperature gauges and thermometers
- Swichgage instruments for pressure, temperature, and level monitoring with built-in shutdown switching
- Liquid level gauges and indicators
- Gauge panels and instrument clusters for compression skids
- Electronic sensors and transmitters for remote monitoring
- SCADA-compatible transmitters and signal outputs
Engineering note: Murphy Swichgage instruments combine a local display with an integrated shutdown switch — a common choice for compression packages where simple, fail-safe protection is preferred over a full PLC panel. Specify the parameter being monitored (pressure, temperature, level) and the desired setpoint range when ordering.
Notes
- Valve selection requires process conditions — pressure rating, temperature, flow media, and connection spec
- Murphy switch gage instruments are SPDT output — confirm compatibility with your panel or control system
- Norriseal-Wellmark relief valves are available in ASME-certified configurations for code-compliant installations
- Kenco level controllers are widely used with pneumatic dump valves on production separators — confirm actuation type when ordering
- Valves and instrumentation available from a single source — reduces vendor complexity
- New and surplus options available on select instrumentation
- Murphy gauges and switch gage instruments stocked for same-day availability on common configurations
- Send your tag list or BOM for a same-day quote
Frequently Asked Questions
Yes. Norriseal-Wellmark safety relief valves are available in ASME-certified configurations for applications where code compliance is required. Specify your required ASME stamp, pressure class, and orifice size when inquiring.
A Murphy switch gage is a mechanical gauge that combines a visual indication dial with an integrated adjustable switch. When the measured parameter (pressure, temperature, or level) reaches the setpoint, the switch actuates — typically triggering a shutdown or alarm. They’re widely used on natural gas compression packages as a simple, reliable protection device that doesn’t require a control panel or PLC to function.
Yes. Provide your pressure class (150#, 300#, 600#, etc.), end type (flanged, threaded, socket weld), material (carbon steel, stainless), and trim requirements and RES Energy Solutions will source to spec across our valve manufacturers.
