3PC Pneumatic Ball Valve BSPT (SUS316, Double Acting, 2000PSI)
Model: PAVP-04(D)
PAVP-04(D) is a high-pressure ball valve combining a precision-cast SUS316 3PC body with a pneumatic double-acting actuator. Supporting a 2000PSI pressure rating and equipped with an ISO5211 direct mounting pad as a standard specification, it is used for high-pressure automatic shutoff 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
- When is the 2000PSI rating required?
- Most domestic industrial lines operate at 10K (approximately 145PSI) or 20K (approximately 290PSI), but high-pressure steam lines, pressurized lines in high-rise buildings, high-pressure water treatment lines, and some chemical transfer lines require the 2000PSI (approximately 138 bar) level. Please share your maximum operating pressure and surge pressure for a rating recommendation.
- How do I choose between double acting and single acting?
- Double acting offers fast response and large torque margin, providing stable operation even at high pressure and high differential pressure. Single acting provides Fail-safe return on air loss and is suited for lines where safety shutoff is critical. Single acting is generally chosen for emergency shutoff on lines supplying flammable or hazardous substances; double acting is chosen when high-speed automated control is the priority.
- What advantage does the 3PC structure provide on high-pressure lines?
- 3PC allows the center body and two end caps to be separated, enabling seat and ball servicing without dismantling the pipeline. Pipeline disassembly itself is burdensome on high-pressure lines and complicates safety management, so the 3PC structure - which allows rapid seat and ball replacement only - is particularly useful for high-pressure automated shutoff valves.
- What accessories can be attached to a pneumatic valve?
- Various accessory combinations can be supplied as integrated packages tailored to site requirements. Common options include limit switch boxes, solenoid valves, and air filter regulators. Please share your site configuration and we will prepare the appropriate combination.
