Electric Actuated Globe Valve Manufacturer in India

Electric actuated globe valves are used for automated throttling, flow regulation and isolation in process piping where controlled linear stem movement is required. Speciality Valve manufactures electric actuated globe valve assemblies according to valve size, pressure class, trim arrangement, actuator thrust, temperature and process medium. The valve and actuator combination is selected according to the required stem thrust, travel, positioning accuracy and control duty.

Electric Actuated Globe Valve Trim and Flow Regulation Characteristics:

Electric actuated globe valve flow characteristics and pressure-drop performance depend on the plug, seat and trim geometry.

Plug and Seat: Provides controlled throttling and shut-off through linear stem movement.
Parabolic Plug: Suitable where finer flow regulation is required.
Cage-Guided Trim: Provides guided plug movement for stable control in suitable designs.
Single-Port Construction: Used for general flow regulation and isolation duties.
Double-Port Construction: Can reduce the net fluid force acting on the plug in suitable applications.

Electric Actuated Globe Valve Body and Trim Material Grades:

Material selection depends on pressure, temperature, fluid compatibility and corrosion conditions.

Material	Common Grades / Options
Carbon Steel	WCB, A105
Low Temperature Carbon Steel	LCB
Stainless Steel	CF8, CF8M, F304, F316
Duplex Stainless Steel	F51
Super Duplex	F55
Special Alloys	Alloy 20 and suitable nickel alloys

Applicable cast or forged material grades depend on the selected Globe Valve body construction and governing material specification.

Trim materials should be selected together with the body material, process medium, temperature, differential pressure and expected corrosion or erosion conditions.

Electric Actuated Globe Valve Actuator and Position Control:

Electric actuator selection should consider required stem thrust, valve travel, differential pressure, seating/unseating force, operating speed and positioning requirements. Electric actuators can be configured for on-off or modulating service depending on the required process function.

Relevant actuator parameters include:

Thrust: Matched to the required stem force.
Power supply: AC or DC according to actuator design.
Voltage: According to actuator model and power requirement.
Frequency: 50 Hz or 60 Hz according to actuator specification.
Phase: Single-phase or three-phase according to actuator design.
Control: On-off or modulating operation, with 4–20 mA control/feedback where supported by the selected actuator and control package.
Position feedback: Available for applications requiring remote valve-position monitoring.
Actuator Ambient Temperature: According to actuator model, enclosure and accessory specification.
Manual override: Available on suitable actuator configurations.

Electric Actuated Globe Valve Construction Options:

Electric actuated globe valves can be configured with different body patterns and trim arrangements according to installation and flow-control requirements.

Straight Pattern: Conventional body arrangement for general process piping.
Angle Pattern: Changes flow direction by approximately 90° while combining valve and piping functions.
Y-Pattern: Provides a more streamlined flow path than conventional globe construction for selected applications.

Bonnet Construction: Bolted or pressure-seal bonnet according to valve design and pressure-temperature duty.
