Product Description
The Festo VZXF is a sturdy universal angle seat valve ideal for applications where gaseous, liquid, or highly viscous media flows must be controlled . Featuring a robust poppet valve design with a piston actuator, this pneumatically actuated 2/2-way normally closed valve offers soft PTFE sealing and is available with stainless steel or gunmetal valve bodies. Actuators can be specified in stainless steel, brass, or aluminum, and various seat and shaft seal materials are selectable for broad media compatibility .
Key Features & Advantages:
Sturdy Universal Angle Seat Valve Design: Reliable soft-sealing poppet valve with a piston actuator provides robust performance for controlling liquid, gaseous, and highly viscous media flows with viscosities up to 600 mm²/s .
Modular Material Selection for Aggressive Media: Valve bodies available in cast stainless steel (1.4408) for aggressive/corrosive media or gunmetal (red brass) for water and neutral fluids. Actuators are offered in high-alloy stainless steel, nickel-plated brass, or aluminum .
Easy-to-Clean Design with High Chemical/Thermal Resistance: PTFE spindle and seat seals provide high chemical resistance, supporting media temperatures from -40°C to +200°C and operating pressures up to 22 bar, while the design allows for simple cleaning .
Long Service Life & High Flow Rates (Kv up to 43 m³/h): The flow-optimized angle seat body minimizes pressure loss, delivering Kv values from 3.3 m³/h to 18.5 m³/h (or up to 6600 L/min) ensuring reliable operation with water, steam, oils, inert gases, and compressed air .
Wide Application & Corrosion Resistance: With a wide operating temperature range for the medium and actuator endurance from -10°C to +60°C, the valve offers corrosion resistance classes CRC 2 (moderate) or 3 (high) depending on material selection .
