Frequently Asked Questions (FAQs) About Industrial Check Valves

To provide you with the information you need, we have compiled a list of frequently asked questions (FAQs) about our industrial check valves for PD blower pumps. Read on to find answers to common queries and gain a deeper understanding of how our high-quality check valves can enhance the performance of your PD blower pump system.


What Are the Four Types of Check Valves?

The four primary types of industrial check valves are swing check valves, lift check valves, ball check valves, and diaphragm check valves.

  1. Swing Check Valves: Also referred to as flapper-type check valves, they feature a hinged disc that swings freely to allow forward flow and prevent backflow.
  2. Lift Check Valves: These valves have a movable disc that lifts off its seat to allow flow and drops back to prevent backflow.
  3. Ball Check Valves: Utilizing a spherical ball, they rest against a seat to block reverse flow and are pushed away by forward flow.
  4. Diaphragm Check Valves: With a flexible diaphragm, they flex away from the seat to allow flow and return to prevent backflow.

What is the Difference Between Check Valve and Backflow Preventer?

A check valve and a backflow preventer are two distinct devices used for different purposes. A check valve is a mechanical device that allows fluid or gas to flow in one direction and prevents reverse flow or backflow. It typically consists of a movable mechanism, such as a disc or a ball, that opens with forward flow and closes to block reverse flow.

A backflow preventer is a more comprehensive device designed specifically to protect potable water supplies from contamination due to backflow. It incorporates multiple valves and mechanisms to prevent the reverse flow of water from entering the main water supply.


Can You Use a Check Valve Instead of a Backflow Preventer?

In some cases, a check valve can be used as a component within a backflow preventer assembly, but it cannot entirely replace a dedicated backflow preventer. While effective at preventing reverse flow in certain applications, a check valve may not provide sufficient protection against potential hazards associated with cross-connections.

Cross-connections are points in a plumbing system where non-potable water (e.g., from irrigation systems, industrial processes, or other sources) can come into contact with the potable water supply. Backflow preventers are designed to address and eliminate these cross-connection risks.


Does an Industrial Check Valve Need to be Installed Vertically?

No, industrial check valves do not necessarily need to be installed vertically. The installation orientation of an industrial check valve depends on its specific design and intended application. While some check valves may have a preferred or recommended orientation, many can be installed in horizontal, vertical, or even angled positions, depending on the system requirements.
