Airtight valves are designed for a pressure of at least 0.1 MPa (1 kgf/cm²) with a manual drive up to 600 mm in diameter in compliance with the requirements specified in DBN V.2.2.5-2023. The valve is made of powder-coated carbon steel in accordance with RAL 5007 Muar. The transported air temperature should be from -20 °C to +40 °C.
