NACOM PTFE STOPCOCKS

NACOMS PTFE STOPCOCK is a precision machined valve that in many ways relates to the function of a ball valve. When the handle points  in the direction of the flow  the valve is fully open. When the handle points perpendicular to the flow the valve is fully off. At 45 degree position the valve is half open thereby has a metering effect.
