Pneumatic Butterfly Valve (SUS304, Double Acting, 10K)

Model: PAVP-13(SS,D)

PAVP-13(SS,D) is a butterfly valve combining a SUS304 body and disc with an EPDM seat and a pneumatic double-acting actuator. With a short face-to-face dimension, concentric construction, and 10K pressure rating as standard, it is used for high-speed automatic shutoff and sequence-control lines in the chemical, plant, water/wastewater, and construction sectors.

Features

• Short face-to-face distance enables installation in confined spaces
• Simple structural design with low defect rate
• Quick open/close for effective fluid control
• High tightness and durability
• Concentric structure with low torque
• First in Korea to apply ISO5211 Direct Mounting Pad

Frequently Asked Questions

How do I choose between SUS304 body and cast iron body?

Cast iron bodies offer excellent cost competitiveness and are widely used as standard for low-corrosion fluids in large-diameter lines such as general industrial water, treated water, and HVAC water. SUS304 bodies have improved corrosion resistance compared to cast iron, allowing use in saline, mildly corrosive fluids, and seawater environments, making them preferred in coastal plants and treated/wastewater lines. Let us know your operating environment and we will guide you to the appropriate specification.

How do I choose between double-acting and single-acting?

Double-acting drives both directions pneumatically, providing fast response and large torque margin, making it suitable for high-frequency repetitive control; however, position retention is uncertain when pneumatic pressure is lost. Single-acting (spring return) enables fail-safe return when air is lost, making it suitable for lines where safety shutoff is critical. Choose double-acting when high-speed automatic control takes priority, single-acting when safety shutoff is the priority.

What is the application range of EPDM seats?

EPDM has excellent durability against water, hot water, and mildly alkaline fluids, and good recovery elasticity in CIP/SIP environments. Swelling can occur with hydrocarbon-based fluids such as oil and fuel, so consider other seat materials such as NBR for those environments.

What accessories can be attached to a pneumatic valve?

We supply integrated packages combining various accessories to meet field requirements. Typical accessories include limit switch boxes, solenoid valves, and air filter regulators. Let us know your field configuration and we will prepare the appropriate combination.
