Gauge Isolator Valves

Browse our selection of gauge isolator valves, available in carbon steel, stainless steel, and threaded configurations. Engineered to protect pressure gauges and instruments across all industries, they are easy to specify, install, and maintain.

At ISIS Fluid Control, our gauge isolator valves are expertly engineered to protect sensitive pressure instrumentation while improving system serviceability. These valves enable operators to safely isolate gauges and other measuring devices from the main process line, allowing for maintenance, calibration, or replacement—without needing to shut down the entire system or depressurise the circuit.

We offer a variety of configurations to meet diverse application needs:

Carbon Steel Gauge Isolator Valves – Durable and cost-effective, these valves are ideal for general industrial environments where corrosion resistance is not the primary concern.

Stainless Steel Gauge Isolator Valves – Designed for harsh or corrosive environments, such as chemical plants, offshore applications, or hygienic systems, offering long-term protection and compatibility with aggressive media.

Threaded Gauge Isolator Valves – Simple to install and highly adaptable, these valves provide a secure, leak-tight seal across a wide range of pressure systems, making them a versatile choice for many industries.

Each valve is manufactured to meet internationally recognised standards, with pressure instrumentation aligned to BS EN 837-1 and temperature gauges conforming to DIN EN 13190. With precise shut-off capability and high mechanical reliability, these isolators are a practical choice for maintaining instrumentation accuracy and operational safety in critical systems.

Backed by our UK-based support team and global distribution capabilities, ISIS Fluid Control is a trusted partner for reliable, high-performance gauge isolator valves across industrial, utility, and process sectors.
