butterfly valve 2.5 inch
PRODUCT DESCRIPTION
pneumatic butterfly valve manufacturers
pneumatic butterfly valve
Pneumatic U Type Flanged Butterfly Valve
Features & Benefits
Simple structure, good interchangeability, and low price.
The stem seal is not easily deformed to avoid the normal stem leakage, and the overall support is good, stable and firm.
With less seat rubber, there is less potential for expansion and it is easier to control the torque within the proper range.
The use of two-piece valve stems with no pin connection, the structure is simple and compact, and maintenance and disassembly are very convenient.
The butterfly board has the function of automatic centering, and the butterfly board and valve seat are closely matched.a
The phenolic back valve seat has the characteristics of not falling o仔 tensile resistance, leakage prevention
and easy replacement.

Product Description
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.
