Control Valves-ECOTROL
ARCA ECOTROL® offers a wide range of innovative solutions designed to fulfil all your control tasks requirements. Whether housing, inner valve, valve seats, stem seals, actuators, or positioners, every detail benefits from the know-how of expert engineers with many years' experience in a wide range of applications.
High-performance valve actuator:
Our pneumatic multi-spring actuators, with robust construction and integrated explosion protection, are characterized by short actuating times, optimized actuating forces, and reliable tight sealing. ECOTROL® control valves are also available with electric or electrohydraulic actuators.
Multi-functional positioner:
The ARCAPRO® 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”.
