Sanitary Type Non Return Vertical Valve is designed to prevent reversal of flow with strict clean conditions. The Vertical Valve opens whenever the pressure below the plug exceeds the pressure above plug due to spring and higher counter pressure presses the plunger valve against the seat to close the valve. The Vertical Valve is manufactured using quality grade raw material which ensures optimum durability along with long lasting trouble free service. Sanitary Type Non Return Vertical Valve is application specific in design and accurate in dimension.
