Specification

PVC Single Union Ball Valve (Black valve)

This is a UPVC single union ball valve, available in different sizes, colors, and different handle styles to meet your market needs. Ball valves are available in two different connection styles (socket and threaded), which gives them more options for use in piping systems.  Mainly used in agricultural irrigation and water supply systems.

The SWD UPVC Single Union Ball Valve is engineered to provide a cost-effective solution for fluid control without compromising on maintenance flexibility. Unlike standard compact valves, the single union design features a detachable end connector. This allows for quick disconnection of downstream equipment (such as pumps, filters, or sprinklers) for cleaning or replacement, without the need to cut the pipe or shut down the entire system.

It is the ideal choice for agricultural irrigation, swimming pools, and general plumbing where budget and functionality must go hand in hand.

Key Features & Benefits

1. Easy Maintenance with Single Union Design
The integrated union nut on the downstream side enables easy disassembly.This means if you need to service a tank or replace a nozzle connected to the valve, you simply unscrew the union nut. This feature significantly reduces downtime and maintenance labor compared to fixed valves.

2. Smooth Flow & Low Pressure Drop
Our PVC single union ball valve features a polished full-bore ball design that ensures maximum flow capacity.The precision-machined interior minimizes friction and pressure loss, making it highly energy-efficient for pump-driven systems.

3. Durable & Corrosion Resistant
Manufactured from high-quality, virgin uPVC resin, this valve offers excellent resistance to aggressive environments, including saltwater, chemical solutions, and fertilizers. It is UV-stabilized for long-term outdoor durability.

4. Leak-Proof Performance
Equipped with premium EPDM or NBR O-rings and a TPV seat, the valve ensures a bubble-tight seal even under fluctuating pressures. Every unit undergoes 100% pressure testing before leaving our factory.
