Pneumatic valve test pressure

Pneumatic valve test pressure is as follows: : gas seal test. ~。 Working temperature: PTFE ℃ or less PPL ℃ or less carbon fiber ℃ or less applicable medium: water, oil, steam P: nitrate class ( Temperature ℃ or less) R: acetic acid class ( Temperature ℃ or less) Design, manufacture, GB/T - Flange connection: JB/T - GB - Structure length: GB - Nominal diameter: DN ~ DNmm nominal pressure: PN. 、. 、. MPa, pneumatic valve test pressure is gone.
