Product Features

  • Full-Bore Design – Zero flow restriction with minimal pressure drop; allows for pigging and efficient line cleaning

  • Premium 316L Stainless Steel Construction – Exceptional corrosion resistance, durability, and compliance with hygienic standards

  • 3-Piece Body Configuration – Easy in-line maintenance and seal replacement without complete removal from pipeline

  • Manual Quarter-Turn Operation – Simple on/off control with visual position indication

  • Lockable Handle – 7-position lock stopper enables valve opening adjustment and 360° rotation for secure operation

  • PTFE Seats & Seals – High-temperature resistance, low friction, and extended service life

  • CIP/SIP Compatible – Hygienic design with no dead zones, fully cleanable in place

  • Blow-Out Proof Stem – Enhanced safety and reliability under pressure

  • Polished Internal Surfaces – Prevents product residue from sticking, ensures contamination-free processing

Key Advantages

  • Unrestricted Flow – Full-bore design eliminates flow restriction, ideal for high-viscosity products

  • Minimal Pressure Drop – Maintains system efficiency and reduces energy costs

  • Superior Hygiene – Dead-leg free design with polished surfaces prevents bacterial growth and ensures product purity

  • Durability & Reliability – Withstands high pressures and temperatures; tested for thousands of cycles

  • Low Maintenance – 3-piece design allows quick seal replacement without special tools, minimizing downtime

  • Versatile Applications – Suitable for food, beverage, pharmaceutical, biotech, cosmetic, and chemical industries

  • Cost-Effective Operation – Long service life and easy maintenance reduce total cost of ownership

How It Works

The Sanitary 2-Way Ball Valve Manual Mod.SIG/39 operates on a simple quarter-turn mechanism. A precision-machined spherical ball with a through-bore is positioned inside the valve body between two PTFE valve seats.

When the manual handle is turned 90 degrees (quarter-turn), the ball rotates within the valve body:

  • Open Position – The bore aligns with the pipeline, allowing full, unrestricted fluid flow through the valve

  • Closed Position – The solid portion of the ball blocks the flow path, providing tight shut-off with zero leakage

The full-bore design ensures that the opening in the ball matches the pipe diameter exactly, enabling pigging (cleaning with a solid projectile) and uninterrupted flow when the valve is open. The manual handle provides clear visual indication of the valve position, and the lockable mechanism allows the valve to be secured at the desired opening setting.
