HIGH FLOW VALVES
Series 70 >> Model 72B Very Large Orifice, Non-Piloted —
2-Way Normally Closed Valve
Super valves that have ratings that formerly required valves of much greater size. They have higher flow at low pressures and have quick media fill or dump for air, inert gases, and oil.
• Largest direct acting (non-piloted) valve we manufacture. • Large orifice.
• High flow at low pressures.
• Gravity feed lubrication with quick media fill or dump.
Note: This valve also available as an operator. Refer to following page.
OPERATING CONDITIONS
Media: Air, inert gases, and oil. (Series 70 pressure ratings may change due to the viscosity of the liquid.)*
Valve Temperature Range: Standard Valves – 0°F (-18°C) to 104°F (40°C) ambient;
0°F (-18°C) to 150°F (65°C) media. Optional Valves – can tolerate much higher or much lower ambient and media temperatures.*
