Azbil Corporation No. SS2-8110-1200 - 5 - Note) 1) " " shows a model with standard actuator. 2) The maximum operating pressure are 10.5 MPa {107 kgf/cm2} for rating of JIS 63K and 14.7 MPa {150 kgf/cm2} for rating of ANSI 900. 3) The upper figures denote operating allowable differential pressure. The lower denote allowable differential pressure at full closure. 4) When inlet pressure is larger than differential pressure when a valve is fully closed, use the inlet pressure for actuator sizing. Model DAP, springless type piston cylinder actuator (with positioner) Note) 1. " " shows a model with standard actuator. 2. The figures are the same for fully open and fully closed position. 3. When inlet pressure is larger than differential pressure when a valve is fully closed, use the inlet pressure for actuator sizing. Table 4 Air-to-open Rating Actuat or model no.
