<body bgcolor="#FFFFFF"> combined stop/check valves straight or angle, with handwheel or with cap from DN 20 up to DN 250 stainless steel range DN 20 and 25) RFF stop/check valves can operate at the same time as both stop valves and check valves. When they are open, they act as check valves, but it is possible to lock them in the closed position, and they act as stop valves. They are identical in design to standard versions of RFF valves. Maintenance and installation procedures are identical to the corresponding RFF standard valve. Stop/check valves can be identified by a groove machined above the bonnet. They are also supplied painted blue to indicate the no-return function. </body>
