Introduction — High Pressure Flanged End Ball Valve for Process Industries
Chemtech Polyplast delivers robust and certified High Pressure Flanged End Ball Valve for Process Industries that demand absolute safety and reliability under extreme conditions. Our high-pressure valves are built to withstand high fluid pressures (up to ASME Class 2500) and elevated temperatures, making them essential isolation devices in critical applications like power generation, oil and gas, and high-temperature chemical processing.
Engineering Excellence for Extreme Conditions
These specialized ball valves feature heavy-duty construction, often utilizing forged or cast steel bodies, along with precision-machined flanged ends (typically raised face or ring-type joint) to ensure maximum integrity against pipe stresses and pressure surges. Key design features include metal seats or highly engineered polymers to maintain a tight seal under high differential pressure, and a fire-safe design for compliance with API 607/6FA standards, guaranteeing safety in hazardous environments.
Applications — High Pressure Flanged Valves
- High-pressure steam lines and thermal fluid circuits.
- Upstream and midstream Oil & Gas isolation and choke lines.
- Boiler feedwater and condensate systems in power plants.
- High-pressure chemical injection and process feed lines.
- Storage and transport of high-pressure industrial gases.

Installation & System Tips — High Pressure Valves
- Verify the valve's pressure and temperature rating against system parameters.
- Use proper lifting equipment due to the substantial weight of high-pressure valves.
- Ensure use of certified gaskets and bolting materials for flanged connections.
- Never rely on the valve as the sole pressure relief device.
- Regularly check for signs of external leakage, especially at the stem packing.
FAQs — High Pressure Flanged Ball Valves
1. What pressure classes do your flanged ball valves cover?
+
Our high-pressure flanged ball valves are available to cover ASME pressure classes from 600, 900, 1500, and up to 2500, suitable for a wide range of industrial high-pressure services.
2. Are these valves suitable for sour gas service (H2S)?
+
Yes, we offer high-pressure ball valves manufactured and tested in accordance with NACE MR0175/ISO 15156 standards, specifically designed and certified for use in sour gas and related corrosive services.
3. What is the significance of a fire-safe design?
+
A fire-safe design ensures that the valve can maintain its pressure-containing and sealing capabilities even after soft seats and seals have been destroyed by external fire, preventing catastrophic leakage.
4. Can these valves be supplied with metal seats?
+
Absolutely. For extremely high temperatures or abrasive media that are incompatible with soft seats, we provide valves with metal-to-metal seating, offering enhanced durability and shut-off integrity.
5. What end connections are available besides RF flanged?
+
In addition to Raised Face (RF) flanges, we also supply Ring Type Joint (RTJ) flanged ends, which are often specified for the highest pressure and temperature applications requiring maximum joint integrity.
