PTFE Stopcock Valves
iPolymer Stopcock Valves are based on an all wetted PTFE design. Ideal for chemical fluid and gas flow shutoff application. Stopcocks are a simpler version of our popular Ball Valves. The handle points in the direction of flow. By partially rotating the quarter turn handle/stem the Stopcock will partially meter the flow. Polytetrafluoroethylene (PTFE) is well suited for clean room and deionized water applications.
These precision-machined devices that function in much the same way as a ball valve. When the handle points in the direction of flow, the valve is fully open; when the handle points perpendicular to the direction of flow, the valve is fully closed; and at the 45 Degree position the valve is halfway open and thereby has a metering effect on the media flow. The iPolymer Stopcock features an all PTFE wetted surface design. The design is ideally suited for harsh chemical and corrosive media and environments. Polytetrafluoroethylene (PTFE) is also well suited to clean room and deionized water applications. The body, stem and ports are constructed from PTFE. For standard applications, external non wetted components are constructed from Polypropylene.
