Description

Plastic check valves are crucial in a wide range of industries where fluid flow control and system integrity are essential.

When selecting a plastic check valve, it’s crucial to consider the suitable material and the pressure rating. It helps to determine the maximum pressure the valve can handle without affecting its functionality. Choosing a valve with a pressure rating that matches your system’s requirements will ensure optimal performance and safety.

They are lightweight, corrosion-resistant, and cost-effective compared to their metal counterparts. These factors make them an ideal choice for installations where weight, durability, and cost-efficiency are vital.

Another significant advantage of plastic check valves is their ability to minimise pressure loss and control pressure surges within the system (such as engineer positive shutoff when needed). These valves help maintain consistent flow rates by preventing backflow and reducing turbulence caused by sudden fluid direction or velocity changes.

Plastic check valves come in various pipe sizes to accommodate different flow installations that you need – from small-scale applications to maximum flow capacity requirements. 

Whatever your piping system application, we have a suitable plastic check valve to ensure a laminar flow and prevent reverse flow.

FAQ's

Available in various sizes, check valves serve a crucial purpose in multiple industries and applications. Its primary function is to prevent the backflow of water or any other fluid in a piping system. This ensures that fluid flow remains unidirectional, preventing any potential damage or disruption to the system.

One of the critical scenarios where a check valve proves its importance is when there is an increase in temperature within a system. As temperature rises, fluids expand, creating potential reverse pressure (backflow). An adequately installed check valve acts as a barrier, allowing liquid to flow in one direction only, effectively preventing any unwanted reverse flow.

The choice between plastic and metal check valves depends on specific application requirements, budget constraints, and environmental considerations.

The apparent difference between the two is body materials.

Plastic check valves, often made from materials such as PVC or CPVC, offer several benefits. They are lightweight, corrosion-resistant, and cost-effective. Industries often utilise them when they need to handle aggressive chemicals or when they have weight restrictions to consider. Plastic valves also tend to be quieter than their metal counterparts.

Metal check valves, typically made from stainless steel or brass materials, offer superior durability and strength. They respond better to pressure, withstanding much higher maximum working pressure and temperatures than plastic valves. They are commonly used in industrial settings where reliability and longevity are paramount.
