| 2way Ball Valve | ISO Flange | Stainless Steel 316 | PTFE | -20°C to +150°C |
| 2way Ball Valve | ISO Flange | Stainless Steel 304 | EPDM | -10°C to +120°C |
| 2way Ball Valve | ISO Flange | Carbon Steel with ASTM A351 CF8 | PTFE | -30°C to +180°C |
| 2way Ball Valve | ISO Flange | Duplex 2205 | Viton | -20°C to +220°C |
Compact ISO Face-to-Face Mounting Design
The 2way flange ball valve with ISO connection stainless steel Khiso follows standardized face-to-face dimensions that simplify integration. Technicians can align bolt holes accurately, reducing fitting time and the risk of leakage. The symmetrical flange geometry supports uniform clamp force and long-term durability.
Flanking Bolt Pattern Benefits
- Compatible with existing DIN/ISO flanged skids
- Simplifies removal and reinstallation during maintenance
- Provides consistent clamping stress on the gasket
Stainless Steel Body and Khiso Trim Options
Manufactured in stainless steel 304 and 316, the body resists corrosion from media and environmental exposure. The trim, including the ball, seats, and stem, can be upgraded to match aggressive fluids and high-cycle applications. This flexibility helps engineers balance upfront cost against lifecycle performance.
Trim Materials and Uses
- PTFE seals for general-purpose applications
- EPDM for water and mildly aggressive service
- Viton for higher temperature and chemical resistance
- Stainless steel versus coated metal options for severe duty
Manual Actuation and Flow Control Characteristics
Designed for quarter-turn manual operation, the valve requires low handle force and delivers quick isolation. The floating ball mechanism ensures tight shutoff, while the streamlined internal cavity minimizes pressure drop. Operators can monitor seat wear through slight increases in handle effort over time.
Performance Highlights
- Low torque for smooth opening and closing
- Effective shutoff in dosing and recirculation lines
- Indication of valve position via handle orientation
- Minimal maintenance when sized within recommended limits
Installation and Maintenance Practices
Correct installation supports long valve life and prevents unnecessary stress on the ISO flange faces. Technicians should inspect sealing surfaces for debris and apply appropriate lubricant to the stem. Routine checks of bolting torque help maintain leak-free connections in vibrating environments.
Key Maintenance Steps
- Verify flange alignment before tightening bolts
- Check gland packing and stem packing for leakage
- Lubricate stem with compatible grease annually or as needed
- Periodically test handle torque and seal integrity during shutdowns
Specification and Application Summary
- Key specs: ISO flange, stainless steel body, 2way flow path, quarter-turn manual actuation
- Typical uses: chemical dosing, utility service lines, packaging machinery
- Selection factors: media compatibility, pressure rating, temperature range, cycle frequency
- Maintenance tips: check bolt torque, inspect seals, lubricate stem, verify handle operation
FAQ
Reader questions
Can this valve be installed in a horizontal or vertical orientation?
Yes, the 2way flange ball valve with ISO connection stainless steel Khiso is suitable for both horizontal and vertical installation. Ensure the flow direction arrow on the body matches the intended media path and verify that downstream piping does not create additional stress on the flange faces.
What is the expected service life under continuous duty?
With proper media compatibility, correct installation, and routine maintenance, these valves often exceed 10,000 operational cycles. Life expectancy depends on fluid abrasiveness, pressure cycles, and adherence to maintenance schedules recommended by the manufacturer.
Is the valve suitable for products that contact food or pharmaceuticals?
When manufactured with certified stainless steel 316 and compliant seal materials, the valve can meet hygiene standards for certain food and pharmaceutical applications. Confirm cleanliness certifications and traceability documentation before specifying for sensitive processes.
How does temperature variation affect sealing performance?
Thermal expansion can influence seat loading and lead to minor changes in shutoff tightness. The valve performs reliably within the specified temperature range, but extreme swings may require material upgrades or spring-assisted seating designs to maintain consistent performance.
