TruDesign 90549 Ball Valve 3/4" BSP Black

TruDesign 90549 Ball Valve ¾” BSP (Black)

The TruDesign 90549 is a high-strength, marine-grade composite ball valve (seacock) featuring female ¾” BSP parallel threads on both ports. Engineered for both above and below the waterline plumbing installations, this valve provides leak-free shutoff control for engine cooling intakes, livewell circulation, deck washdowns, and grey/black water overboard discharges.

Manufactured in New Zealand from high-rigidity, glass-reinforced nylon composite with PTFE-coated ball seats and a stainless steel spindle core, the valve is completely immune to galvanic corrosion, electrolysis, and dezincification. The smooth internal bore ensures maximum fluid flow rates with minimal pressure drop, while the ergonomically designed lever handle provides smooth quarter-turn operation even after extended periods of inactivity.

Key Features

• Immune to Galvanic Corrosion: Non-conductive composite construction eliminates electrolysis and stray-current corrosion, removing the need for electrical bonding wires.

• ISO 9093-2 & ABYC Certified: Fully approved for above and below the waterline installations on commercial and recreational vessels.

• High Chemical & Freeze Resistance: Unaffected by diesel, petrol, bilge chemicals, acid washes, and winterizing fluids; composite body flexing prevents freeze-cracking.

• PTFE Seats & Seals: Polymer ball seats paired with a smooth composite ball ensure low operating torque and zero binding over years of service.

• Lockable Handle Position: Lever handle features an integrated lock-off tag pin hole to prevent accidental opening of critical underwater hull valves.
