Vulcathene Air Admittance Valve

The Vulcathene Air Admittance Valve is designed to optimise the functionality of laboratory drainage systems by allowing for the internal termination of Vulcathene stacks, thus avoiding the need for costly roof penetrations. It prevents the release of foul air and admits air under reduced pressure to protect water seals in traps, contributing to the ventilation of the main drain.

• Prevents Foul Air Release: Designed to stop foul air from escaping the drainage system, maintaining a clean and safe laboratory environment.
• Pressure Regulation: Admits air under reduced pressure conditions to prevent water seals in traps from being compromised, ensuring the effective operation of the drainage system.
• Easy Maintenance: Features a removable screw cap for straightforward access during maintenance procedures.
• Flexible Installation: Comes with a rubber finned tail for internal pipe connection, making it adaptable for various setups. A 102mm to 76mm reducer can be used to enable connection to a 76mm Vulcathene stack.
• Standards Compliance: Approved to BS EN 12380 (B1), indicating compliance with high-quality and safety standards.

• Product Codes: V466040
• Available Sizes: 102mm
• Approvals: BBA 24/7091
• Material: Black Co-Polymer PP  (a unique composite engineered for chemical resistance and UV protection).
• Temperature Range: Suitable for temperatures from -20°C to +100°C.
• Applications: Laboratory drainage.

Creating a secure mechanical joint with Vulcathene fittings involves a precise and methodical process to ensure optimal joint integrity and system performance. Follow these steps for installation:

1. Cutting the Pipe:
   • Use a rotary plastic pipe cutter for a clean, burr-free cut. Clamp the pipe to avoid distortion.
   • Ensure the cut is square. If a hacksaw is used, remove all burrs and loose material.
   • Groove the pipe using the appropriate grooving tool for the tongued olive to fit in.
2. Grooving:
   
   • Insert the pipe fully into the grooving tool.
   • Adjust the blade depth to about half and rotate the tool anti-clockwise around the pipe.
   • Increase the blade to full depth, continue rotating, then remove the tool and clear any swarf.
3. Assembling the Joint:
   
   • Slide the nut onto the pipe, with the threaded side facing the groove.
   • Insert the olive (widest end first) into the groove. Use Vulcathene lubricant for ease, especially with larger sizes.
   • Ensure the olive is correctly seated and the fitting thread is clean. Apply lubricant to the fitting threads.
   • Loosely assemble the joint and hand-tighten the nut using two Vulcathene spanners, then tighten fully to ensure a secure fit.

Note:

• Tighten nuts progressively during installation, not all at once at the end.
• Use the Vulcathene grooving tool and spanners to guarantee the joint's integrity.
