Brass Proportional Safety Valve Threaded Herose 06205

TECHNICAL DESCRIPTION

Automatic safety valve, opening proportionally to pressure rise. The constant force between the pressure force and the reaction of the closing spring ensures a minimum flow, respectively fluid consumption when the valve is actuated. Full opening, at 10% overpressure of the valve setting. When ordering a valve, please inform us of your requirements regarding valve capacity, fluid type, temperature, inlet size and the type of system in which it will be used. Standard safety valve with FPM seat seal, open bonnet with unloading windows and forced opening device. Thread type G (BSPP) according to ISO 228/1 Used as a safety device in the event of excessive pressure rise in stationary systems and mobile gas cylinders and pressure vessels. Suitable for air and similar gases. Operating temperature: -20°C / -4°F (253K) up to +160°C / +320°F (433K), size d07 also suitable for horizontal installation.

WORKING FLUID / MEDIUM

Liquids, gases, steam.

EXECUTION

Only upon request:

  • stainless sealing ring – stainless steel 1.4571.
  • external nickel coating on the valve.

Dimensions: DN 1/2″ – 1 1/4″


Description

The HEROSE 06205 Brass Proportional Safety Valve is a precision-engineered industrial component designed for reliable pressure regulation in demanding applications. This threaded proportional valve features a durable brass construction that ensures excellent corrosion resistance and long-term performance in various fluid handling systems. Its proportional design allows for precise control of pressure release, making it ideal for maintaining system safety and efficiency. Key features of this safety valve include: Proportional pressure relief mechanism for accurate control Threaded connections for secure installation and leak prevention Brass body construction for durability and corrosion resistance HEROSE quality certification for industrial standards compliance Compact design suitable for space-constrained installations This valve is specifically engineered for industrial applications including steam systems, compressed air networks, hydraulic systems, and process control installations. The proportional safety mechanism ensures gradual pressure release rather than sudden discharge, preventing system shocks and maintaining operational stability. With its threaded connections, the valve offers easy integration into existing piping systems while maintaining a secure, leak-proof seal. The HEROSE 06205 meets rigorous industrial standards and is suitable for working pressures up to specified limits. Its brass construction ensures compatibility with water, air, steam, and various non-aggressive media. This valve represents German engineering excellence and is backed by HEROSE’s reputation for manufacturing high-quality industrial valves since 1902.
