Product Description
The Festo VTOP is an innovative, modular, and compact complete solution for pneumatic control applications, bringing order to your regulation tasks by eliminating complex external piping . This valve terminal allows you to expand a positioner with modules such as a volume booster, fail-safe unit, and filter regulator—all combinable as required without external tubing . Featuring a patented integrated air duct that supplies all modules, the actuator, and the positioner, the VTOP is easy to install, simple to maintain, and can be extended or retrofitted without any problems .
Key Features & Advantages:
Patented Integrated Air Duct: Features a revolutionary integrated air duct that supplies all modules, the actuator, and the positioner without leak-prone, external piping, significantly reducing potential leakage points and installation complexity
Modular and Customisable Design: Modules such as fail-safe, volume booster, and filter regulator can be freely combined as required, are easy to install, and can be extended or retrofitted without problems, allowing you to precisely tailor the valve terminal to your application needs
Four Core Functional Modules: Available modules include the Filter Regulator PCRI for air quality and pressure regulation, Volume Booster VOGM for increased flow and faster actuation speeds, Fail-Safe module VOGI for double-acting actuators (moves to safe position on pressure failure), and Flange Module VABP for safety exhaust functions on single-acting actuators
Standardised Mounting Interface: Features a standardised mounting interface for direct attachment of a positioner according to VDI/VDE 3847-2, optimised for positioner CMSH for controlling single- and double-acting quarter-turn and linear actuators
Extreme Durability & Corrosion Protection: Rated with Corrosion Resistance Class CRC 3 (high corrosion stress), suitable for harsh industrial environments, with an ambient temperature range of -40°C to +80°C
High Flow Capacity (Volume Booster): The VOGM volume booster delivers a Kv value of 1 (approximately 1,000 l/min), enabling significantly faster actuation speeds for critical control applications
Precise Pressure Regulation (Filter Regulator): The PCRI filter regulator offers an output pressure range of 0.5 to 8 bar with 5 or 40 μm filter fineness, includes a pressure gauge connection and an actuation lock for security
Fail-Safe Functions for Single or Double-Acting Actuators: Configurable fail-safe functions for single-acting actuators (via flange module VABP, safety architecture HFT0 or HFT1) or double-acting actuators (via pneumatic fail-safe module VOGI with air receiver connection)
Reversible Direction of Action: An integrated reversing plate in the end plate VABE allows reversal of the direction of action for double-acting pneumatic actuators without additional components
Suitable for Quarter-Turn and Linear Actuators: Compatible with quarter-turn actuators DFPD-C with mechanical interface to VDI/VDE 3847-2 and linear actuators DFPI-NB3 based on ISO 15552
Optimised for CMSH Positioner: Specifically optimised for the CMSH smart positioner, offering integrated self-monitoring and diagnostic features for complete automation of globe valves and quarter-turn actuators
Reduced Connection Efforts: The modular VTOP incorporates individual components and reduces connection efforts significantly compared to conventional solutions with external piping
Easy On-Site Maintenance: Modules can be replaced or serviced on-site to ensure maximum reliability and utilisation without dismantling the entire assembly
CE Certified: Carries CE marking as per EU conformity declaration
