Product Description

Info

BAC PQR-i is a flanged, reduced-bore floating ball valve for shut-off duties in chemical, gas, LPG and oil & gas processes. The one-piece body is intended for installations where a compact reduced-bore valve is suitable for the hydraulic and process requirements. AxFlow can support selection based on line size, pressure class, materials, process medium and the required operating or automation concept.

The PQR-i construction combines a one-piece body and floating ball with relief seats, an anti-static device, a pressure-balance hole in the ball and a blow-out-proof stem. A self-adjusting double stuffing box supports stem sealing. BAC specifies fugitive-emission performance to ISO 15848 and wetted internal parts in accordance with ANSI/NACE MR0175/ISO 15156.

BAC lists PQR-i in Class 150-300 from 1/2 x 3/8 inches up to 12 x 10 inches. The valve is designed to ISO 17292 with ASME B16.5 RF flanges, ASME B16.10 short-pattern face-to-face dimensions and an ISO 5211 top flange. Fire-safe testing is stated to EN ISO 10497 / API 607, while available options include API 6D, cryogenic service and an emissions-control port.

For engineering and maintenance teams, the reduced-bore geometry should be checked against acceptable pressure drop and process requirements before selection. Standardized flanges, face-to-face dimensions and actuator mounting help simplify mechanical and automation integration. Correctly matching the body and trim materials, class rating and optional execution to the actual duty supports reliable isolation and predictable lifecycle maintenance.

What is the BAC PQR-i used for?

BAC PQR-i is used for industrial process isolation where a reduced-bore flanged ball valve is suitable. Typical application areas listed by BAC include chemical, gas, LPG and oil & gas service. AxFlow can help verify whether the reduced-bore geometry is appropriate for the required flow and pressure-drop conditions.

What size and pressure range is available for BAC PQR-i?

BAC lists PQR-i in Class 150-300 from 1/2 x 3/8 inches to 12 x 10 inches. The reduced-bore designation means the flow passage is smaller than the connecting pipe size. Selection should therefore consider both mechanical fit and hydraulic requirements.

Which standards apply to BAC PQR-i?

BAC specifies ISO 17292 design, ASME B16.5 RF flanges and ASME B16.10 short-pattern face-to-face dimensions for PQR-i. The top flange is to ISO 5211 and fire-safe testing is stated to EN ISO 10497 / API 607. Project-specific certification and option requirements should be confirmed for the ordered configuration.

What options are available for BAC PQR-i?

BAC lists API 6D, cryogenic service and an emissions-control port as available options for PQR-i. The suitability of each option depends on the process and project specification. AxFlow can help identify the required execution before quotation.

Can AxFlow help replace an existing PQR-i valve?

AxFlow can support replacement by checking pressure class, connection size, reduced-bore dimensions, materials and actuation. Face-to-face and flange standards should be compared with the installed valve before ordering. Contact AxFlow for technical support, availability and a quotation.
