Sanitary Non-return-Valve ( Vertical NRV )

Ambika has designed spring-assisted check valve (Sanitary NRV) for Vertical mounting to prevent flow reversal in industries. The internal surface finish is 0.8 Ra while the disc and seat are lapped to provide excellent shutoff. 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.

  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.
