Zero Stem Leakage

Metal bellows form an absolute barrier between the fluid medium and atmosphere — zero leakage at the stem under all operating conditions.

Double Seal Design

Bellows plus packing backup seal — if the bellows fail, the packing provides a secondary seal, ensuring continuous leak-tight operation.

Conical Disc Design

Streamlined conical disc removes impurities from the seating surface, maintaining reliable sealing and extending valve service life.

Bellows Protected Space

On Extend and Super series, bellows are housed in a sealed protected space — isolated from medium, pressure and temperature for maximum corrosion resistance.

Titanium Triple Seal

Extend series titanium seal element provides a triple seal — delivering superior reliability in high temperature and highly corrosive applications.

Double Stem Construction

Super series combines upper and lower stem in wear-resisting and anti-corrosion materials, meeting the most demanding wear and corrosion resistance requirements.

High Quality Casting

German coated sand casting technology achieves surface smoothness of 12.5–25 microns with over 98% of castings free from pores, blisters and cracks.

Y-Type Flow Optimised

Y-Type straight flow structure reduces fluid resistance, accelerates flow rate and minimises pressure loss — ideal for viscous or caking media.

Angle Type Space Saving

90° outlet eliminates the need for a separate elbow fitting at pipeline corners, saving installation space and reducing potential leak points.

High Pressure Rated

ANSI High Pressure variant features automatically welded bellows at both ends forming a robust metal barrier suitable for high pressure service.

DIN · ANSI · JIS Standards

Full coverage across the three major international standards, ensuring compatibility with existing pipeline systems and project specifications worldwide.

Wide Application Range

Suitable for process plants, chemical, pharmaceutical, power generation and industrial applications requiring reliable zero-leakage globe valve performance.
