3PC Electric Ball Valve BSPT (SUS316)
Model: PAVE-03
PAVE-03 is a ball valve combining a precision-cast SUS316 3PC body with an electric actuator. With a BSPT threaded connection and an ISO5211 direct mounting pad as standard specifications, it is used for remote automatic shutoff and sequence-control lines in the chemical, plant, water/wastewater, and construction sectors.
Features
- Compact design for easy installation in confined spaces
- 3PC structure for easy installation and maintenance
- Leak tested per API598
- First in Korea to apply ISO5211 Direct Mounting Pad
Frequently Asked Questions
- How do I choose between electric and pneumatic?
- Pneumatic offers fast operation speed and easy fail-safe configuration via spring-return; however, it requires auxiliary equipment such as compressed air, filters, and solenoids. Electric only requires power for installation and offers easy maintenance, but operation is slow and unsuitable for high-frequency cycles. Choose electric for fields without pneumatic facilities or when only a few valves need automation; choose pneumatic for processes requiring high frequency or fail-safe.
- What options can be added to electric actuators?
- Various options are available depending on application. First, small-diameter valves can be configured with approximately 1-second high-speed open/close specifications, suitable for lines requiring fast ON/OFF repetition. Second, for sections requiring continuous flow control, proportional control specifications that control opening with 4-20 mA input signals can be selected. Third, explosion-proof actuator specifications are available for areas handling flammable gas or ignitable liquids.
- How is the 3PC structure's maintenance convenience utilized?
- 3PC has a separable central body and end caps, allowing seat, ball, and seal maintenance without dismantling the piping. Lines with frequent regular inspections or suspected seat damage allow rapid maintenance by separating only the central body, resulting in short line downtime.
- What happens to the valve when power is interrupted?
- Standard electric actuators maintain the current position when power is cut. If automatic return to a specific position is required when power is lost, an actuator specification including battery backup or spring-return is required, so let us know your fail-safe requirements and we will guide you on whether the option can be applied.
