Official distributor and authorised service centre in Ukraine
- Inlet pressure

TENZORA · SR26
Purpose
Combined direct-acting two-stage gas pressure regulators. They reduce the pressure of pre-filtered non-aggressive gases and keep it at the set level regardless of inlet pressure and flow variations. They automatically shut off the gas supply on excessive flow, outlet over- or under-pressure, and vent excess gas to atmosphere on impermissible pressure rise.
Applications
- Natural gas distribution systems
- Fuel gases of the 1st, 2nd and 3rd families per EN 437
- Pipelines with pressure up to 0.6 MPa
Benefits
Stable outlet pressure
The two-stage system with a balanced first stage holds outlet pressure regardless of flow and inlet pressure.
Protection in one body
Over/under-pressure slam-shut, relief valve and filter are already integrated.
No part replacement over service life
When installed and operated correctly, the regulator needs no maintenance involving part replacement — only inspections and functional checks.
Certified in Ukraine
Type-examination certificate (Module B) and manufacturer’s quality system certificate (Module D) issued by SE “SVTsOO”.
