The DiversiTech NRV38 is a precision-engineered non-return valve featuring a 3/8-inch connection size. Often referred to as a check valve, this component is essential for ensuring that fluid or gas flows in one direction only. By preventing backflow, it protects the system from contamination and mechanical failure caused by reversed pressure or liquid return.

This valve is specifically designed to fit standard 3/8-inch piping or tubing, facilitating a secure and leak-proof connection in condensate management systems. It is a critical replacement part for maintaining the efficiency of high-performance pumps, ensuring that once water is expelled from the reservoir, it cannot flow back in.

Why It Matters

Without a functional non-return valve, condensate pumps may suffer from constant cycling as water drains back into the tank after the pump shuts off. This leads to premature motor wear and increased energy consumption. The NRV38 provides a simple, mechanical solution to keep your drainage system operating at peak efficiency while preventing potential water damage from reservoir overflows.

What's Included

• ✓ 1 x DiversiTech NRV38 Non-Return Valve (3/8" Connection)

Features & Benefits

• Unidirectional Control: Effectively permits flow in one direction while strictly blocking the opposite path.
• Low Opening Pressure: Operates with a sensitive opening pressure of 0.08 – 0.1 bar, allowing for easy fluid passage.
• Pressure Resilience: Rated for a maximum working pressure of 1.0 bar, ideal for standard condensate applications.
• Specific Compatibility: Seamlessly integrates with Little Giant VCMA, VCC, and VCL series pumps.
• Robust Construction: Designed to withstand the moisture and varied temperatures found in HVAC drainage environments.

Applications

• Condensate pump installations (Little Giant VCMA-20S, VCC-20S, and VCL-24S).
• HVAC drainage lines requiring 3/8" braided hose connections.
• General low-pressure fluid transfer where backflow prevention is mandatory.

Tradie Pro Tip

When replacing this valve, always ensure the discharge tubing is clean and free of slime or algae buildup. Even a new check valve can fail to seat properly if debris from the hose gets lodged in the mechanism. A quick flush of the lines before installation goes a long way!
