Pneumatic Fully Lined Butterfly Valve

The lining butterfly valve body is a split type combination. Easy to assemble and seal adjustment, when the valve is working, only the fluoroplastic seat and the fluoroplastic valve plate are in contact with the medium.
The inner surface of the valve body channel is smooth, the fluid resistance is small, the CV value is high, the circulation capacity is strong, the torque is moderate, and the zero leakage of the medium is completely achieved. The valve is small in size, light in weight, compact in structure, rapid in switching, beautiful in appearance, and excellent in craftsmanship. Reliable performance, light operation, long service life.
The valve can withstand any corrosive media other than molten alkali metals and elements. It is a gas, liquid, semi-fluid pipeline and container for chemical, petroleum, pharmaceutical, food, steel smelting, papermaking, hydropower, and environmental protection systems. Do a quick cut-off and adjust the best product for your device.
Lining materials: PTFE, FEP, PFA, GXPO, etc.
Connection form: clip type, flange type, lug type connection
Drive mode: manual, turbine, electric, pneumatic

Product Description

All listed output torques are expressed in inch pounds of torque (in. lbs.).
Charts for available air pressure are expressed in pounds per square inch (P.S.I.).
FLOWX actuators offer ±5° adjustment in the open and closed positions on DA52 through DA-125 models.
For all other models, adjustment is in the open position only.
The closed position is 0° fixed. Optional retrofit kits are available to allow for adjustment in both open and closed positions on the DA-160, DA-200 and DA-270 models.

General Application

Ideally suited for many applications within the heating ventilation and air conditioning, water treatment and irrigation markets.
