Control and Monitoring Solutions

Remote Mount

Digital valve positioners mounted remotely in a cabinet are ideal for harsh environments and any application with difficult or limited access to the actuator.

Cabinets available: NEMA 4/4X or for hazardous areas.

Manual override customized to suit your application.

Direct Mount

No mechanical linkage requirement gives you the flexibility to mount directly on the actuator or the valve in any orientation.

A2A Booster

A2A Systems are significantly smaller and lighter than a conventional air tank system.
They are up to 85% smaller and up to 45% lighter providing a more economical solution.

Volume Booster

Volume boosters are recommended with larger modulating actuators for smooth operations. Typically required for 10″ bore and above. Booster can be installed either directly on the AT or in a remote panel.

GT3 Gland for Harsh Environments

Triple-seal gland with dual wipers. Rugged metallic scrapper and urethane double-acting wiper deflect contamination away from the rod seal for long service life.

Options:

Low Temp

Cast Iron construction for applications where yellow metals are not allowed
