Check Valves

Are critical safety elements in fluid systems that allow liquid or gas to flow in only one direction, automatically preventing backflow to ensure pump and equipment safety. ORFA Industrial offers a wide range of check valves that prevent water hammer and maximize sealing, with various material options. Professional check valves with stainless steel, cast iron, and brass bodies secure the flow direction in your system while extending system life with ORFA quality.

What Are Check Valves and Why Should They Be Used?

Check valves are mechanical valves that require no energy and prevent fluid from flowing in the reverse direction through a closing mechanism. Used in pump outlets, hydropneumatic tank systems, and heating lines, these products protect equipment by preventing water from draining back when the system stops. ORFA Industrial recommends using high-quality check valves to maintain piping stability and provide safety against potential water hammer. Professional equipment that opens with the pressure of the flow and closes under its own weight or with the help of a spring when the pressure drops minimizes the risk of leakage. Check valves, with different hydraulic structures, play a vital role in the continuity of industrial processes. Choosing a quality product saves energy and directly increases system efficiency.

Types and Technical Designs of Check Valves

Different model options are available in our stock based on the installation method and the characteristics of the fluid. The main check valve product groups offered by ORFA are as follows:

Structural Types

  • Swing Check Models — Low pressure drop and for large diameter lines.
  • Disc Type Products — Compact design and wafer type connection.
  • Spring-Loaded Mechanisms — Mountable in any orientation and silent closing.
  • Ball Check Systems — Ideal for wastewater and sewage lines.

Application Areas

  • Building hydropneumatic tank groups and central water installations.
  • Wastewater treatment and drainage pump stations.
  • Steam lines and condensate return systems.
  • Chemical, food, and pharmaceutical industry transfer circuits.

Correct Check Valve Selection and Installation Criteria

The success of a system depends on selecting check valves suitable for the pressure class of the pipeline and the chemical structure of the fluid. Choosing the wrong valve type can lead to noisy operation or loss of sealing on the installation. With ORFA's engineering expertise, we determine the most durable check valve configuration for your project, ensuring system safety. Modern designed check valves adapt to all temperature ranges with their sealing gasket options. High-strength professional equipment protects the system against water hammer, reducing maintenance costs. Investing in quality check valves prevents mechanical failures by stopping the pump from turning backwards. Using reliable products in industrial facilities is the most fundamental requirement for long-term operational continuity.

Frequently Asked Questions

Can check valves be installed in a vertical line?

Spring-loaded type check valves can be installed in both horizontal and vertical lines. However, swing check type models generally should only be used in horizontal lines as they operate on the principle of gravity.

How are check valve prices determined?

Prices vary depending on the DN size of the equipment, the type of body material, the sealing type, and the pressure rating class.
