Ductile Iron Service Valve Female x Male Thread PN16

  Data Sheet.pdf

The Blucast PN16 ductile iron service valve with internal and external threaded ends provides reliable isolation for utility service lines and potable water networks. Engineered for demanding municipal and industrial environments, this compact shut-off valve features female by male threaded connections across sizes from 1 inch to 2 inches, enabling space-saving installation between tapping saddles, water meters, and distribution mains. As an authorised Blucast dealer, BigWeld delivers these heavy-duty utility components directly to engineering sites across Europe.

Constructed with a robust GGG-25 ductile cast iron body, this valve delivers exceptional mechanical endurance and resistance to ground subsidence compared to conventional cast iron fittings. Sealing integrity is maintained by a resilient EPDM seat designed for continuous contact with drinking water and neutral fluids. The valve stem is precision-machined from AISI 416 stainless steel, preventing corrosion, minimizing operating torque, and guaranteeing dependable shut-off even after extensive periods of inactivity. All cast surfaces receive an automatic powder epoxy coating with a minimum dry film thickness of 250 microns in RAL 5015 sky blue, ensuring comprehensive passivation against aggressive soils and chemical attack.

Key technical characteristics and operational parameters:

• Body material: GGG-25 ductile cast iron
• Resilient sealing seat: EPDM elastomer
• Drive stem: AISI 416 stainless steel
• Nominal pressure rating: PN16 (16 bar working pressure)
• End connections: female x male BSP threaded joints in sizes 1", 1 1/4", 1 1/2", and 2"
• Corrosion barrier: electrostatically applied powder epoxy coating, minimum 250 microns, RAL 5015
• Operating temperature range: neutral fluids from 0 degrees to 80 degrees Celsius
• Target applications: municipal drinking water networks, sewage networks, pumping stations, irrigation infrastructure, and industrial utility piping

The valve is fully compatible with standard street boxes and extension spindles, providing installers and network operators with a maintenance-free isolation solution for long-term underground service.
