Single Seat Globe Regulating Valve is a top-guided regulating valve that can be equipped with pneumatic (multi-spring diaphragm/piston actuators), electric smart actuators.
For pneumatic modulating service, confirm the selected actuator, positioner and control arrangement. The required accessories depend on the specified duty and signal.

Frequently Asked Questions
Should I request the pneumatic or electric version of this single-seat valve?
Choose the operating package in the inquiry rather than assuming both drives are included. Provide the available air or electrical supply, control duty and command and feedback requirements, and request the selected assembly specification.
What process data do you need to size the single-seat trim?
Provide the medium, minimum and maximum flow, inlet and outlet pressures and temperatures for each operating case. Request model-specific sizing and trim confirmation; pipe diameter alone is not enough to approve the selection.
How can I check whether the quoted pneumatic package includes the controls I need?
Ask for the actuator, positioner and accessory schedule together with the proposed signal interfaces and failure response. Confirm the supplied configuration against your control-system requirements before placing the order.
