The Welker Automatic Insertion Temperature Probe is designed for use in operations where it is necessary to determine pipeline temperature for measurement or analysis. The design of the unit allows the operator to control the movement of the probe into and out of a pressurized pipeline safely by utilizing pipeline pressure and manipulating four valves. […]
Capture fugitive emissions before they enter the atmosphere with Welker’s latest patent-pending solution! Install the LeakHawk™ Leak Detection Manifold to a pump for advanced on-site or remote notification of the need for pump seal maintenance so you can catch and proactively repair leaks. The LeakHawk™ is a simple, cost-effective device that can be used to […]
The ISPE model in Welker’s I-Series Instrument Regulators is a cost-effective, standalone piston-sensing instrument regulator suitable for regulating air and light gases, such as hydrogen. With global and industrial decarbonization goals, the development and deployment of hydrogen and fuel cell technologies are growing in importance. Welker’s ISPE Instrument Regulator can be used across the hydrogen […]
The Welker HR Heated Instrument Regulator is a single-stage, spring-loaded, electrically heated pressure reducing valve designed to provide an analytical system with a conditioned gas sample stream at a safe output pressure and temperature. The HR’s controlled heating compensates for the cooling brought on by the Joule-Thomson effect to prevent condensation and maintain sample integrity.
For real-time natural gas analysis of high-volume lines, you need a sample probe that can deliver a continuous supply of representative samples to your analyzer at the appropriate pressure. The Welker Original IRD Probe Regulator mounts directly to a hot tap or mating flange on your depressurized pipeline and has a fixed insertion length to […]
The Welker IRA-4SS Probe Regulator is designed to regulate a gas sample stream without interrupting pipeline flow. With AI Control™, the probe automatically inserts and retracts using pipeline pressure.
Is there something in the air? You may be in an explosive atmosphere. Knowing these hazardous locations require specially designed equipment to reduce the risk of fires and explosions, Welker updated the design of its patented HR-4SS Heated Regulator specifically for this purpose. The Welker HR Heated Instrument Regulator is a single-stage, spring-loaded, electrically heated […]
Powering and protecting your pneumatic instruments just got easier thanks to the spring-loaded Welker I-Series Instrument Regulators. The ISD model reduces high-pressure filtered gas or air to a lower outlet pressure safe for your downstream instrumentation, helping prevent costly damage and interruptions to operation.
When trusting the process isn’t enough, get your eyes on it. With a Welker SG Sight Glass in the line, technicians can visually observe fluid flow on site to ensure sampling and injection systems are functioning properly.
The Welker RV-110 series Relief Valves are ideal for protecting high capacity gas instrumentation from overpressure events. Designed with ASME standards in mind, these safety devices have a 10% overpressure relief capacity and are made in America from stainless steel.
