GD-47R Pressure Regulating Valve – Engineered for Stable Steam Control

The GD-47R Pressure Regulating Valve is a direct-acting, external sensing type valve designed specifically for steam applications. It offers stable regulation even under varying flow conditions, making it suitable for demanding industrial environments.

Key Features

  • Designed for heavy-duty use across a wide flow range

  • External sensing type for accurate pressure detection

  • Bellows structure with stainless steel components

  • Minimal differential pressure requirement: 0.05 MPa

  • High temperature resistance up to 220°C

  • Valve seat leakage rate of 0.5% or less of rated flow

  • JIS 10K FF flanged connection

Its ductile cast iron body (FCD450) combined with stainless steel valve, seat, and bellows ensures durability and corrosion resistance in steam systems.
