Model W

Operating Conditions

Maximum internal pressure is 2 to 6 barg (29 to 87 psig), depending on glass diameter. Vacuum values are available on request. Maximum temperature is 200°C (392°F) with PTFE blades, and 180°C (356°F) with silicone.

Options and Accessories

W wipers are for use on all KB series, model SS, model SSTC sight glasses, and model AKF sight flow indicators.
