THE VAMECA ADVANTAGE: DEDICATED TECHNICAL SUPPORT

THE VAMECA ADVANTAGE: DEDICATED TECHNICAL SUPPORT

A PSQ tailored to your valve

Our valve expertise allows us to evaluate the complete valve and actuator assembly—including actual torque, mechanical interfaces, and electrical operation. We then match your specific requirements against the configurations available in our local inventory.

Valve and Assembly

Actual Torque

Record the breakaway, running, and seating torques.

Shaft and Flange

Please provide the square drive, keyway, flange, and all available dimensional specifications.

Stroke and Travel Stops

Check the operating angle, direction of rotation, and end stops of the assembly.

Power Supply and Control

Power Grid

Please specify the voltage, number of phases, and actual operating frequency, specifically 60 Hz.

Actuation Type

Please specify on/off, floating control, or modulating control with a positioner.

Operating Conditions and Environment

Specify the operating cycle frequency and ambient temperature.

A photo of the nameplate, the mounting dimensions, and the required operating parameters are all we need to get started. VAMECA will deliver a tailored configuration featuring the optimal technical options and a confirmed delivery timeline.

Specify required application or function

Accessories are selected using the part number and its corresponding wiring diagram.

Control

PSAP Positioner

Supply-dependent positioning option. This should not be confused with standard position feedback.

Signage & Identification

Switches and Transmitters

Additional limit switches, PD potentiometer, and PSPT transmitter are available depending on your configuration.

Environment

Tailored Protection

IP68 ratings, corrosion protection, and low-temperature models are available depending on the part number. Please note that ambient temperature is distinct from media temperature.
