We have been producing control valve positioners of the highest quality since 1961, offering the widest range of valve positioners to complement any application in any industry. To enable you to drive your process at its best, we manufacture valves with these criteria in mind:
Fast Commissioning with user-friendly backlight LCD with full test and menu
Full Valve Compatibility with the largest range of mounting kits/accessories for valve manufacturers
Widest Application Coverage with High Flow/Pressure version, Remote Mounting, and Modular designs for inter-operability and practicality
Premium features like Partial Stroke Test (PST), Fugitive Emission Monitoring, and FDT-DTM are also available
Smart Positioners
Intelligent Control Valve Positioner SRD998
The SRD998 offers a wider choice of pneumatic performance, including high flow versions and up to 10 bars of air supply and output pressures available.
High output pressure allows the positioner to work at a higher torque on the actuator and valve; therefore, smaller actuator sizes can be used. Very high flow capacity versions enable savings since small volume boosters are unnecessary.
Robust and Reliable Design
Savings in maintenance and spares with innovative modular design
Reduced accidental damage during commissioning with a single user dedicated compartment for cabling and configuration
Increased lifetime thanks to a 2-stage filtering system and overpressure protection of the internal I/P
User-Friendly Interface
Fast commissioning with one “Turn and Push” rotary selector and intuitive menu
Increased comfort of use with large backlit full-text display
Reduced installation and shutdown time due to online troubleshooting with local help files
Designed to be mounted to control any valve in any application
Inventory and installation costs are reduced with integrated high airflow capacity versions (up to Cv 0.85)
Seamless DCS integration
SRD960 Positioner Intelligent Valve Control - Ex d
Offering the latest technology in the market, the SRD960’s features include an infrared interface for wireless operation and configuration, a multilingual full-text graphic LCD, and availability with the choice of all in the process automation applied communication protocols.
Its enhanced applications and methods can also analyse recorded stroke data. All the diagnostics features can be easily configured and displayed by the Positioner DTM (VALcare). The Positioner DTM enables you to edit a complete “health” report of the valve with all data of configuration and diagnostics.
The SRD960 can even control a Partial Stroke Test (PST) that offers operators a tool to identify the trouble-proof function of ESD (Emergency Shut Down) valves.
SRD991 Intelligent Valve Control
The SRD991 offers the most advanced technology available on the market today. This includes, among others, an infrared interface for wireless operation and configuration, a multilingual full-text graphic LCD, and availability with the choice of all in the process automation applied communication protocols.
It offers enhanced applications and methods to analyse recorded stroke data. All the diagnostics features can be easily configured and displayed by the Positioner DTM (VALcare). Moreover, the Positioner DTM enables editing of a complete “health” report of the valve with all data of configuration and diagnostics.
The SRD991 also has the capability to control a Partial Stroke Test (PST) that offers operators a tool to identify the trouble-proof function of ESD (Emergency Shut Down) valves.
Analogue & Traditional Positioners
SRP981 — the result of more than 50 years of experience with pneumatic positioners
SRI986 — more than 1 million applications worldwide
SRI983 — the classic explosion-proof solution
SRI990 — the analogue positioner; easy operation and compact design
The Result of 5 Decades of Industry Experience & Expertise
Our traditional range of positioners, SRP981, SRI986, and SRI983, are the results of 50 years of experience in the field. These positioners are designed for the operation of pneumatic valve actuators with pneumatic (SRP981) or 4-20mA (SRI986 and SRI983) control signals.
Extraordinary Reliability & Economy
They are used to reduce the adverse effects of valve friction for higher thrust and shorter positioning time. Our durable pneumatic components offer extraordinary reliability and economy, even under difficult climatic conditions.
Easy Adjustment & Conversion
The analogue positioner SRI990 with analogue input 4 to 20 mA is designed to operate pneumatic valve actuators. It offers easy adjustment using switches and potentiometers. The modular structure of this positioner series enables conversion from an analogue to an “intelligent” positioner by exchanging the electronics.
The RMU998 Remote Mounting Unit is the solution for valve/actuator applications in harsh environments, such as operating the valve at very low or very high temperatures and high vibrations.
Volume Booster
VBSX00 Volume Booster Series is designed to operate pneumatic valve actuators via a valve positioner. It is recommended for large actuators to reduce positioning time. The bypass valve adjusts dynamic response, providing stable operations over a wide range of actuator sizes.
Filter Regulator
FRS0X is a dedicated filter regulator for direct mounting to valve positioners with pneumatic performance “High Air Output.” Control of instrument supplies air pressure and removes dust particles and water content by filtration to drive pneumatic actuators.
