Description:
Non return valves or check valves are spring loaded valves that installed on hydraulic system to allow fluids flow in a single direction only. There is one inlet and one outlet for check valves which will show a directional marking on the valve body. This is to ensure that users install the check valves in correct direction wherein fluids will flow into inlet and flow out from outlet. A minimum working pressure is required in the fluids system for check valves to work. Inteva series check valves are metal closing check valve applicable in hydraulic oil applications. It can withstand up to 420 BAR working pressure. The available connections are in compression end connection and threaded connection which is NPT and BSPP. |

Product Information of High Pressure Check Valves
|
1. Specifications:
High pressure check valves or non return valves are valves that allow fluids to flow in one direction only. It also mean that it is use to prevent the return flow of the fluids. Check valve is a two opening valve where one for fluids to enter and one for fluids to flow out. There is a directional arrow that marked on the valve body to show the valve inlet and outlet. For check valve, it will need a cracking pressure to push the poppet for fluids to flow through. For more details, please refer to inteva.es/check-valves. For Inteva series check valves, it was designed as metal closing system and made accordance to European Directive 97/23/EC. It is suitable for oil hydraulic applications in marine and offshore industry. |

6. Installation of High Pressure Check Valves:
Various techniques can be used to complete the installation process.
Various techniques can be used to complete the installation process.
- First step is to inspect inner of the wall to remove any possible production materials. There should be no foreign material inside the check valve, as this could cause it to malfunction.
- It is necessary to test the valve's operation by pushing it away from the seating surface. The most crucial thing is to make sure it can freely move.
- Inspection of both ends to ensure that there are no burrs or edges that could cause resistance during the sealing process is critical.
- To improve functionality or workability, put the check valve in the opposite direction of the flow.
- The cover must be orientated to the top if the valve is installed horizontally or vertically. Checking flow control of a valve allows unrestricted flow in one direction while restricting flow in the opposing direction.
