Acetylene Single-Stage Regulator RED111 with Pressure Relief Valve

Engineered for precise acetylene control, the RED111 regulator delivers a maximum inlet pressure of 25 bar and a stable outlet pressure of 1.5 bar, making it a reliable choice for demanding welding, brazing, and cutting applications. Its forged brass body and EPDM diaphragm ensure durability and consistent performance even in harsh workshop environments.

Overview

The RED111 acetylene regulator is a single-stage device designed to reduce high cylinder pressure to a safe, usable level for oxy-acetylene equipment. It features a W21.8 x 1/14" LH inlet connection for standard acetylene cylinders and a G 1/4" LH outlet for hose attachment. Two pressure gauges provide clear readings: inlet pressure up to 25 bar and outlet pressure up to 2.5 bar. The integrated pressure relief valve (PRV) adds an extra layer of safety by venting excess pressure automatically.

What stands out

• Forged brass body for long-lasting strength and corrosion resistance
• EPDM diaphragm ensures consistent regulation and long service life
• Integrated pressure relief valve protects against over-pressurization
• Clear dual gauges for inlet and outlet pressure monitoring
• Complies with EN ISO 2503 for safety and performance
