Specification

PN16 Y Type Bellow Seal Globe Valve (Manual, Flange & Butt Welded)

I. Product Overview

VALVEFAC PN16 Y type bellow seal globe valve is a versatile flow control solution engineered for industrial pipelines, featuring manual operation and dual connection options (flange, butt welded). Crafted with WCB, stainless steel, and forged steel, it combines a Y-type flow path with a bellow seal structure to balance precise regulation and zero leakage. Operating at -20℃~425℃, it leverages a stainless steel bellow to eliminate stem leakage—critical for media like water, steam, and light oil. Compliant with international standards, it is ideal for general industrial systems, heating circuits, and medium-pressure pipelines, where reliable sealing and flexible installation are key.

II. Key Attribute Parameters

Size Range: Covering common industrial diameters (e.g., DN80), adaptable to small to medium pipelines.
Pressure Rating: PN16 (1.6MPa), suitable for low to medium-pressure systems such as heating networks and auxiliary steam lines.
Temperature Range: -20℃~425℃, with WCB/stainless steel retaining stability in high-temperature media like steam.
Material Configuration:
- Body: WCB (cost-effective), stainless steel (corrosion resistance), or forged steel (enhanced strength).
- Bellow: Stainless steel, forming a hermetic barrier between stem and media to prevent leakage.
- Seal: Stainless steel or Stellite (wear-resistant), ensuring tight shut-off under frequent operation.
- Stem: Stainless steel, isolated from media by the bellow to avoid corrosion and ensure smooth movement.
Connection Types: Flange (for easy disassembly) and butt welded (for leak-tight, permanent installation).
Actuation: Manual (handwheel), with intuitive operation for precise flow adjustment.
Design Standards: Complies with industrial norms for dimensions and performance, ensuring compatibility with global pipelines.
