Ball Valve wafer - Type FC2 | ADLER

ADLER FC2 Wafer Full-Bore Ball Valve

Wafer-type full-bore ball valve for on/off isolation in industrial piping systems with elevated pressure ratings. The short body pattern is installed between DIN or ANSI flanges and reduces face-to-face length compared with conventional flanged ball valves.

Technical Data

• Nominal sizes: DN15–DN300
• Pressure ratings: PN63, PN100, PN160
• Series range: PN16–PN160 / ANSI Class 150–1500
• Body materials: ASTM A105N, ASTM A479 Type 304, ASTM A479 Type 316
• Seat material: PTFE
• Connection: wafer, between flanges
• Flange standards: DIN or ANSI, according to selected version
• Automation: pneumatic or electric actuator

Suitable Media

Applicable to steam, water, compressed air, neutral gases, selected aggressive gases and liquids, provided that the body metallurgy, PTFE seat and operating temperature are compatible with the fluid and process conditions.

Operational Conditions

The full-bore design limits pressure drop in the fully open position and is suitable where line pressure loss must be controlled. Wafer installation requires accurate flange alignment, correct gasket selection and uniform bolt tightening to avoid pipe stress being transferred to the valve body.

Material Selection

• ASTM A105N: carbon steel body for general industrial services and non-corrosive fluids.
• ASTM A479 Type 304: stainless steel for process water and mildly corrosive environments.
• ASTM A479 Type 316: stainless steel for higher chloride exposure or more demanding corrosion conditions.

Sealing and Leakage Considerations

PTFE seats provide tight shut-off in compatible temperature and chemical ranges. Seat wear, cycling frequency, differential pressure and entrained solids should be checked during valve sizing. For steam service, operating temperature and pressure must be verified against the seat limits.

Typical Applications

• Steam and condensate isolation lines
• Compressed air headers and utility manifolds
• Water treatment and process water systems
• Chemical transfer lines with compatible fluids
• Skid-mounted process units where compact face-to-face length is required

Standards, Documentation and Automation

Selection is normally based on DN, PN or ANSI class, flange standard, material grade, seat compatibility and actuator duty. Material certificates such as EN 10204 3.1 may be specified when required by the project. Pneumatic actuators are used for plant air systems and fast operation; electric actuators are selected where electrical control, slower stroking or remote positioning is required.

Variant Comparison

• Higher PN or ANSI class increases pressure capability but may affect actuator torque.
• Carbon steel versions are used for general utility service; stainless versions are selected for corrosion resistance.
• Manual operation is suitable for infrequent use; actuation is selected for interlocks, remote isolation or automated shutdown sequences.

FAQ

Is the FC2 suitable for throttling? It is primarily an isolation valve. Continuous throttling can damage the ball and PTFE seats.

What must be checked before ordering? DN, pressure class, flange standard, temperature, differential pressure, fluid compatibility, leakage requirement, actuator torque and cycle frequency.

Can it be used on steam? Yes, if pressure, temperature and seat limits are confirmed for the steam condition.
