Electric Actuated Gate Valve Manufacturer in India

Electric actuated gate valves are used for automated isolation where a straight-through flow path and remote multi-turn operation are required. Electric actuated gate valve selection should consider valve size, pressure class, process temperature, differential pressure, stem design, seating load, material compatibility and actuator torque/thrust requirements. Electric multi-turn actuators control stem movement to open and close the valve.

Electric Actuated Gate Valve Construction for Automated Isolation:

Electric actuated gate valves are designed primarily for isolation rather than continuous throttling. Common construction features include:

• Wedge or parallel gate arrangements

• Rising or non-rising stem designs

• Bolted or pressure-seal bonnet construction according to valve design, pressure-temperature duty and applicable specification

• Metal or resilient seating

• Full-bore configurations

• Manual override for suitable actuator arrangements

Electric Actuated Gate Valve Pressure, Size and Connection Parameters:

Applicable Standards and Testing:

Depending on the valve design and application, relevant standards may include:

• Open/close functional test

• Full-stroke verification

• Open and closed limit-position checks

• Torque/thrust setting verification where applicable

• Position indication/feedback check where provided

• Manual override function check where provided

• Electrical/control interface check according to actuator package

Electric Actuated Gate Valve Material Options:

Material selection is based on operating pressure, temperature, process medium and corrosion conditions.

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

Gate, stem, seating surfaces and other wetted components should be selected as a compatible material system for the process medium, temperature, pressure and corrosion conditions.

Multi-Turn Electric Actuator Arrangement:

Electric actuation for Gate Valves requires a suitable multi-turn actuator selected for the required stem torque, axial thrust, travel and seating/unseating loads. Actuator configuration is determined by valve size, seating load, operating cycle and control requirements.

Key actuator parameters include:

• Torque and thrust: Matched to valve operating requirements.

• 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: Primarily on-off operation; intermediate positioning only where specifically permitted by the selected Gate Valve design and application.

• Mounting: ISO 5210 or applicable multi-turn actuator interface.

• Actuator Ambient Temperature: According to actuator model, enclosure and accessory specification.

Electric Actuated Gate Valve Stem and Seating Arrangements:

The stem and seating configuration influences isolation performance and actuator requirements.

• Rising Stem: Provides visible indication of stem movement and valve position.

• Non-Rising Stem: The stem does not rise externally during operation, reducing vertical space requirements where this design is suitable.

• Wedge Seating: Provides shut-off through interaction between the gate and seats.

• Parallel Seating: Uses parallel gate/disc and seat surfaces in suitable Gate Valve designs for isolation service.

• Metal Seating: Selected where process temperature, media, wear or service conditions require metallic seating surfaces.

• Resilient Seating: Used for compatible media and operating conditions.

Electric Actuated Gate Valve Applications:

• Pipeline Isolation – Remote shut-off on oil, gas and process pipelines.

• Tank Farm Piping – Isolation of storage and transfer lines.

• Steam Lines – Automated isolation in suitable pressure and temperature conditions according to the selected Gate Valve design, materials and pressure-temperature rating.

• Pump Systems – Automated isolation on suitable suction or discharge piping.

• Process Plant Piping – Remote isolation where manual operation is difficult or impractical.
