Little Giant CV-10 Check Valve 1/4″ MNPT to 3/8″ Barbed Black

Description

Product Overview

The Little Giant CV-10 check valve is a purpose‑built component designed to work exclusively with Little Giant condensate removal pumps, including the VCL‑14, VCL‑24, VCMA and VCC series. Constructed from high‑grade acetal, the valve body offers excellent chemical resistance and dimensional stability, ensuring a long service life even in demanding industrial environments. The sealing system combines a nitrile O‑ring and a Buna‑N (Nitrile) ball, delivering a leak‑free barrier that prevents reverse flow of condensate back into the pump. With a 1/4‑inch male National Pipe Tapered (MNPT) inlet and a 3/8‑inch barbed outlet, the CV‑10 fits standard 1/4‑inch vinyl tubing, making installation straightforward for technicians and DIY installers alike. The valve is painted black for a modern appearance that blends seamlessly with other pump components, and its compact 1.72‑inch length by 0.72‑inch diameter footprint allows it to fit into tight spaces without compromising performance.

Usage

Designed for continuous operation in HVAC, refrigeration, and industrial water‑handling systems, the CV‑10 check valve excels wherever condensate must be moved away from equipment without the risk of back‑pressure. It is ideal for commercial building basements, data‑center cooling loops, and manufacturing facilities where condensate pumps run 24/7 and any reverse flow could cause equipment damage or costly downtime. The valve’s robust construction tolerates up to 290 bars of operating pressure, making it suitable for high‑temperature steam condensate applications as well as low‑temperature cooling condensate. Because the valve prevents water from re‑entering the pump, it eliminates rapid cycling—a common cause of premature pump wear—thereby extending the lifespan of the pump and reducing the frequency of maintenance visits. Installers appreciate the simple 1/4‑inch MNPT to 3/8‑inch barbed connection, which requires only a standard wrench and a short length of vinyl tubing to achieve a secure, leak‑free fit.

Why Choose Us

When selecting a check valve for condensate removal, reliability, material quality, and compatibility are paramount. Little Giant, a trusted brand under Franklin Electric, brings decades of engineering expertise to every component, and the CV‑10 is no exception.

FAQ

What pumps are compatible with the CV‑10 check valve?

The CV‑10 is engineered specifically for Little Giant condensate removal pumps in the VCL‑14, VCL‑24, VCMA and VCC series. It will not function correctly with other pump brands or models that have different inlet/outlet sizes.

Can the valve handle high pressure applications?

Yes. The valve is rated for a maximum operating pressure of 290 bars, making it suitable for both low‑temperature cooling condensate and high‑temperature steam condensate systems.

Is any special tooling required for installation?

No special tools are needed. A standard wrench to tighten the 1/4‑inch MNPT connection and a short piece of 3/8‑inch vinyl tubing for the barbed side are all that’s required for a secure, leak‑free installation.

What maintenance is required for the CV‑10?

The valve is designed for maintenance‑free operation. Periodic visual inspections to ensure the tubing remains secure and free of damage are recommended, but the internal components do not require regular replacement.

How does the CV‑10 improve pump performance?

By preventing condensate from flowing back into the pump, the CV‑10 eliminates rapid cycling, which is a primary cause of premature pump wear. This results in smoother pump operation, reduced energy consumption, and longer service intervals.
