Pressure Release Valves (PRV)

(Overpressure Protection System for Biogas Plants & Storage Units)

In biogas and CBG systems, maintaining stable and safe pressure levels is absolutely essential for reliable plant operation. Excess pressure resulting from sudden gas generation, pipeline blockages, or equipment malfunction can severely damage digesters, gas holders, and pipelines — and in extreme cases, may lead to hazardous failures or explosions.

To effectively control such risks, TECTIKO offers highly dependable and precision-engineered Pressure Release Valves (PRVs) — specifically designed to safely discharge excess gas pressure while ensuring complete protection of your biogas infrastructure and critical equipment.

Working Principle:

  • The TECTIKO PRV functions as an automatic safety mechanism that activates when internal system pressure rises beyond a predetermined safe limit.
  • Once normal pressure conditions are restored, the valve automatically reseats to securely seal the system.
  • TECTIKO PRVs ensure uninterrupted safety, operational stability, and long-term reliability without affecting continuous plant performance.
