Sanitory Non-return Valve ( Horizontal NRV ) |
|||||||||||||||
 |
Description | ||||||||||||||
Ambika has designed spring-assisted check valve (sanitory NRV) for horizontal mounting to prevent flow reversal in industries. In horizontal NRV the line of flow is eccentric for the flow output and because of this the fluid flowing through the NRV does not stay at seat due to gravitation force. This help for better operation in horizontal mounting as well less effect of back pressure in valve. The conventional NRVs are in same line of flow which do not have this feature. The specially designed end connection is easy for mounting and dismounting and so it is comfortable for maintenance and less time consuming. Additionally body and seat, is fastened with a quick release clamp and elastomeric body seal to permit fast and easy access to the internals. |

Principle of operation |
|||||||||||||||
In line spring assisted NRV is designed to prevent reversal of flow with strict clean condition. The valve opens whenever the pressure below the plug exceeds the pressure above the plug due to spring and higher counter pressure will press the plunger valve against the seat to close the valve. |
