2PC Pneumatic Ball Valve Flange (SUS304, Single Acting)

Model: PAVP-10(S)

PAVP-10(S) is a ball valve combining a precision-cast SUS304 flanged 2PC body with a pneumatic single-acting actuator. With a 10K flange rating and an ISO5211 direct mounting pad as standard specifications, it is used for automatic shutoff and fail-safe lines in the chemical, plant, water/wastewater, and construction sectors.

Frequently Asked Questions

How is the fail-safe direction set for single-acting?
Single-acting can be configured to automatically return to Fail Close or Fail Open via spring force when pneumatic pressure is lost. Flammable or hazardous material supply lines require automatic shutoff during air loss, so Fail Close is selected; lines such as cooling water or rinse water that must maintain supply use Fail Open. Provide your process safety requirements and we will prepare the spring direction to that specification.
What flange specifications are available?
The standard flange specification for PAVP-10(S) is JIS 10K, but it can be changed to other international standards such as KS, ANSI, and PN according to project requirements. Provide the flange specification and bolt hole arrangement of your existing line and we will prepare the appropriate specification.
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.
How do I choose between 2PC and 3PC?
2PC has fewer parts, reducing leak points and offering price advantages. 3PC allows seat and ball maintenance without dismantling the piping, making it advantageous for lines with short maintenance intervals. General automatic shutoff lines often use 2PC, while lines with frequent maintenance often use 3PC.
