Key Features
GKV18C/16N/16H Series Control Valves

- Characterized by short actuating times, optimized actuating forces, and reliable tight sealing. 
- GKV18C/16N/16H control valves are also available with electric or electrohydraulic actuators.
Multi-functional positioner:

- The GK2300 digital positioner is a multi-functional interface with integrated bus support for the controller or process control system. 
- Installation and mechanical connection to the valve actuator are compliant with VDI/VDE 3847 guidelines for open, non-proprietary concepts.
Reliable stem seals:

- From the stuffing box to the hermetically-sealed bellows, this stem seal can be tailored exactly to the process fluid, pressure, and temperature required. 
- The design, stem surface, and packing material complement each other perfectly to avoid problems with friction, corrosion, and emissions.
Fixed-form housing seal:

Our design connects the valve housing and the bonnet in the force bypass, and the housing seal is clamped in place preventing it from “yielding”.
Robust, high-precision valve trims:

- These are specially designed for the prevailing flow conditions in your plant. 
- The shapes of the throttle valves and valve seats and the material from which they are made are optimized to meet your requirements. 
- Our valve seats integrate the unique quick-exchange system and can be replaced without special tools. 
- The float-mounted clamping seat and the metal or soft seal for the valve seat ensure leak-tight, reliable sealing.
