BK1 - ABS Double union ball valve

Product catalog summary

Product Overview

The ABS Double Union Ball Valves BK1, manufactured by Polypipe Italia, are designed for low temperature fluid transport with good chemical resistance, lightweight construction, and ease of use. These valves feature a floating full bore ball locked on both sides and a machined ball for optimal sealing. They allow sealing adjustment and disassembly via a key incorporated in the handle and are available in actuated versions.

Specifications

Nominal Pressure: PN 15 at 20°C
Dimensions: DN 15 to DN 100 (3/8" to 4")
Valve Material: ABS
Seals Material: O-rings in EPDM or FKM; Ball seats in PTFE
Temperature Range: -40°C to 60°C
Coupling Standards: Solvent welded sockets compliant with BS standards
Control Options: Manual, electrically actuated, pneumatically actuated

Compliance and Certifications

The valves comply with the Pressure Equipment Directive 2014/68/EU, Annex III, Module A2. NSF and WRAS certifications apply only to valves with EPDM seals and are valid for items listed officially.

Operating Parameters

Maximum Operating Pressure: Varies with temperature as per provided graph (up to PN 15 at 20°C)
Flow Rates (l/min): Range from 190 l/min (DN 15) to 10,000 l/min (DN 100)
Torque Force at Max Pressure: Ranges from 1.5 Nm (DN 15) to 30 Nm (DN 100)
Flow Coefficient (Kv100): Provided for pressure differential of 1 bar

Actuation and Mounting

BK1 valves can be actuated using standard electric or pneumatic actuators with a dedicated mounting kit (BDRKITB1). The mounting flange conforms to ISO 5211 standards. Valves from DN 15 to DN 50 include integrated threaded inserts for fastening, with optional wall mounting plates (BDR1BASE/BDR1BASF).

Components

The valve assembly includes ABS nuts, sockets, gasket carriers, body, stem, and ball; EPDM or FKM O-rings; PTFE ball seats; and PVC-U handles. Threaded inserts are brass for DN 15 to DN 50.

Product Variants and Dimensions

Detailed dimensional tables are provided for manual and actuated valves, including electric (12 V, 24-240 V AC/DC) and pneumatic double-acting versions. Each variant lists codes for EPDM and FKM seals, nominal diameters, lengths, mounting dimensions, pressure ratings, and weights.

Installation and Usage Recommendations

Use solvent welded sockets compliant with BS standards for coupling.
Choose seal material (EPDM or FKM) based on chemical compatibility and certification needs.
Actuation kits and mounting accessories should be selected according to valve size and application.
Regular maintenance and sealing adjustment can be performed via the handle key.
