TESCOM Anderson Greenwood primary isolation valves are engineered to provide a secure, dependable first line of isolation between the process and downstream instrumentation.

This extensive range includes models such as M50/H70, H70DB primary root valves, F68/F69, F29/F33K, F63/F64, F66/F73/F73K, P62, P63, HD27M/HD27MK, HD29, HD33M/HD33MK, HD7M/HD7MK, and the H70W series, all designed to deliver reliable shut-off and high-pressure containment in demanding industrial environments.

Commonly specified in oil and gas, chemical processing, power generation, hydrogen, and industrial measurement systems, these primary isolation valves protect gauges, transmitters, and analysers while allowing safe maintenance, calibration, and system shutdown without compromising process safety.

Supporting the primary isolation valve range are complementary Anderson Greenwood instrumentation products including HM25D and HM1C hand valves, the A27M instrument isolation gauge block, H64T/H64F Keyblok interlock manifolds, BR Series flushing and bleed rings, and the H2 valve series.

Together, these solutions enhance operational safety by enabling controlled isolation, venting, flushing, and interlocking to prevent incorrect valve sequencing or uncontrolled pressure release.

Manufactured from high-quality materials and designed for long service life, TESCOM Anderson Greenwood primary isolation and hand valve solutions reduce leak paths, simplify installation, and improve overall system integrity.

TESCOM primary isolation valves are engineered to provide secure, dependable shut-off at the very start of the instrumentation chain. Installed between the process and sensitive measurement equipment, they allow systems to be safely isolated for maintenance, calibration, or shutdown while protecting gauges, transmitters, and analysers from high pressure and sudden surges. Built for demanding industrial environments, Tescom primary isolation valves deliver reliable sealing, high-pressure capability, and long-term performance where safety and system integrity cannot be compromised.

TESCOM primary isolation valves provide the first line of isolation between the process and downstream instrumentation such as gauges, transmitters, and analysers.
