Pressure Relief Valve Ysf16 70 130kkj For Transformer Oil System - China

Pressure Relief Valve YSF16-70*130KKJ for Transformer Oil System Pacitan Power Plant

Product Introduction

The YSF16-70*130KKJ is a directional oil-injecting pressure relief valve for Pacitan Power Plant’s coal-fired units in Indonesia.

It protects oil-immersed transformers by instantly releasing excessive pressure within 2ms during faults, then reseals to keep the tank positive pressure and block impurities.

Product Features Opening pressure 70kPa (±5kPa), 130mm oil injection diameter, with dual electrical and mechanical alarm signals (KKJ).

Alloy steel and brass body, working at -30℃~50℃, directional oil injection to sump for fire safety.

Automatic reset at 37.5kPa, reliable sealing to avoid medium leakage and ensure long-term operation.

Applications Safety protection for main transformers and on-load tap-changers in the plant.

Prevents tank deformation/explosion from internal faults like short circuits and overheating.

Core safety component for stable power transmission of the plant’s thermal units.

The above is for reference only.
