INTRODUCTION

A check and stop valve is the combination of a stop valve and a check valve that features the functionalities of both valves. When the valve is opened, the fluid flows in the direction of the arrow, and the valve seat is closed in case of countercurrent to prevent the backflow of the fluid. The stainless steel stem and the Teflon sheet of this valve ensures a long life span and can be useful in a minimal installation space.
