Establish a secure, high-flow discharge system on your water towers, buckets, ponds, and fish tanks with our premium UPVC water tank drain valve assembly kits, available at Atradesen.com. Crafted from potable water-grade and chemical-grade UPVC, this complete mechanical kit is engineered to withstand up to 16kg (1.6 MPa) of pipeline pressure. It provides a leak-free, ready-to-assemble drainage switch that hooks directly into flexible soft hoses.
Featuring standard parallel pipe threads, this linear assembly ensures massive flow volume and extremely low pressure loss, making it the exceptional choice for bulk water discharge and routing.
Each package comes fully equipped with all necessary professional installation components, eliminating the need to source separate fittings:
| Feature | Details |
|---|---|
| Material | Industrial Potable-Grade UPVC (Lead-Free & Non-Toxic) |
| Thread Standard | Standard G-Thread / BSP Parallel (Bulkhead locknut is reverse-threaded) |
| Maximum Pressure Rating | 1.6 MPa (16kg / 232 PSI) |
| Working Temperature Range | 0°C to 55°C (32°F to 131°F) |
| Hose Clamp Material | Premium 304 Stainless Steel with integrated thumb-turn key |
Q: Why does the bulkhead locknut tighten counter-clockwise (reverse thread)?
A: When you screw a standard right-hand threaded ball valve onto the bulkhead's external threads, the clockwise turning force would normally loosen a standard bulkhead nut. The left-hand (reverse) thread design ensures that tightening the ball valve actually locks the bulkhead nut even tighter against the tank wall, preventing accidental loosening and leakage.
Q: What can I connect to the inner socket port of the bulkhead connector?
A: The inner port features a standard smooth socket designed for solvent welding. You can glue in a rigid PVC pipe to act as a standpipe, a vertical overflow bypass, or an intake screen, allowing you to control the water level from inside the tank.
