WTA® Stop-Check Valve Type 19.1

Features And Benefits

• The stop-check valve combines the functional characteristics of a check valve with those of a bellows sealed globe valve.
• Only one valve is needed in a section where previously two valves had to be used.
• If the valve stem is in the open position (hand wheel in upper position), the valve works like a conventional check valve; the medium can move in the flow direction; the plug closes in the event of backflow.
• The spring loaded plug holds the valve in closed position so that the valve can be mounted in any position.
• If the valve stem is in closed position (hand wheel in lower position), the valve works like a conventional stop valve; the plug remains closed with flow from any direction.
