Is the Ball Valve with Aluminum Butterfly Handle, BSPT Male, Type 4424 compatible with chemical media at elevated temperatures up to +150°C?

Ball Valve with Aluminum Butterfly Handle, BSPT Male, Type 4424 can be used with chemical media at temperatures up to +150°C provided the chemicals are compatible with the valve materials. The valve construction: nickel‑plated brass body, chrome‑plated brass ball, PTFE ball sealing and FKM + NBR stem sealing — determines chemical resistance. PTFE offers excellent chemical resistance and high‑temperature stability; FKM (Viton) performs well with many chemicals at elevated temperatures; NBR has more limited resistance, especially to strong acids, ketones and aromatic hydrocarbons, and its temperature/chemical limits can be lower. Therefore, before use at +150°C you must verify each chemical’s compatibility with brass, PTFE, FKM and NBR and confirm allowable working pressure at that temperature. If any media attack these materials, select a valve with more suitable materials or seals.

Can the Ball Valve with Aluminum Butterfly Handle, BSPT Male, Type 4424 maintain full pressure ratings across its temperature range up to +150°C?

Ball Valve with Aluminum Butterfly Handle, BSPT Male, Type 4424: No — the valve does not maintain a single full pressure rating across the entire temperature range up to +150°C. The product description explicitly states that the working pressure is dependent on temperature. While the valve is rated to operate between -20°C and +150°C and is constructed from durable materials (nickel-plated brass body, chrome-plated brass ball, PTFE ball seal, FKM + NBR stem seal), maximum allowable pressure will decrease at elevated temperatures. For exact pressure limits at specific temperatures, consult the manufacturer’s pressure–temperature chart or technical datasheet.
