WELKER > New Product

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 value chain to reduce the pressure of the hydrogen gas to a lower outlet pressure safe for the downstream equipment in your application, helping prevent costly damage and interruptions to operation.

ISPE

Reduce methane emissions with Welker’s proven technology! The design of the Accu/Line™ Zero Emissions includes all the key features of the Accu/Line™ family of smart odorant injection systems but eliminates the use of pipeline gas as the instrument supply, meaning no natural gas is released during normal operation.

This Accu/Line™ is a turnkey odorant injection system designed to inject liquid odorant proportional to flow into natural gas pipelines with flow rates from 10 Mscfh up to 70 MMscfh.

Zero Emissions Accu/Line

Tired of getting burned by your odorant flare? Welker now offers a high-quality alternative!

Rooted in Welker’s commitment to creative, quality solutions, we engineered the SafeBurn™ to exceed your expectations. Safe, portable, and easy to use, the SafeBurn™ Odorant Flare is designed to burn off odorant vapors and blanket gases from tanks up to 1000 gallons prior to maintenance or decommissioning.

SafeBurn

ATEX/IECEx Heated Regulator

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. The HR is specifically designed for use in explosive atmospheres.

Instrument Regulator

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.
