Product Overview
The PN16 Wafer Ball Valve with ISO5211 Direct Mounting Pad is a highly compact, premium-grade industrial valve engineered for precise fluid shut-off and flow control.
Designed specifically for space-restricted environments, its ultra-short face-to-face wafer body structure allows seamless installation clamped directly between pipeline flanges, significantly reducing overall system weight and piping footprints.
Automation-Ready Design
Featuring an integrated ISO 5211 mounting platform, this valve eliminates the need for costly and bulky brackets or drive couplings.
It allows direct installation of pneumatic and electric actuators, minimizing backlash while improving automation reliability and operational efficiency.

Key Features
ISO 5211 Direct Mounting Platform
Allows direct actuator installation without mounting brackets, reducing installation costs and improving system stability.
Blow-Out Proof Stem
The stem is internally retained within the valve body to prevent accidental ejection under pressure.
Dual Anti-Static Design
Continuous electrical conductivity between ball, stem, and body safely dissipates static electricity.
Floating Ball Seat Technology
Utilizes line pressure to create bubble-tight sealing performance with minimal leakage.
Full Bore Flow Path
Provides maximum flow efficiency while minimizing pressure loss.
Compact Wafer Construction
Reduces installation space requirements and overall system weight.

Frequently Asked Questions (FAQ)
What are the advantages of a wafer ball valve?
A wafer ball valve offers a significantly shorter face-to-face dimension and lower weight than conventional flanged ball valves, making it ideal for compact piping systems.
Why is ISO 5211 important?
ISO 5211 provides a standardized interface between valves and actuators, enabling direct mounting without additional brackets or couplings.
Can this PN16 valve be installed between PN40 flanges?
Yes. The flange dimensions are compatible with PN10, PN16, PN25, and PN40 flange standards. However, the valve operating pressure remains limited to PN16.
Which material should I choose: WCB or CF8M?
WCB is recommended for non-corrosive services such as water, steam, and oil.
CF8M (316 Stainless Steel) is recommended for corrosive chemicals, marine environments, food processing, pharmaceutical, and fine chemical applications.
