两位四通换向阀 卫生级换向阀  Sanitary Reversing Valve

应用:该换向座阀是一种卫生级单座气动操作阀门，在食品加工工业，饮料生产制药和精细化工工业中有着广泛的应用。

操作原理该座阀由单作用或双作用的气动执行器自动操作。压缩空气推动轴来定位阀门开或关的位置。

单作用执行器的气缸180度的旋转，实现了阀门的常开和常闭型。

设计和特点阀体采用国内锻压设计

尺寸从DN25/1“到DN100/4"   标准为常闭型阀门(NC)

通过简单的改变气动执行器的活塞，阀门就可以转变成常开型(NO) 根据3A 标准卫生设计  360度可调节外部结构  开启的窗口用于观看检查轴密封情况通过松开卡箍，就可以简单的拆卸内部部件    焊接式连接口(毫米或英寸)

Sanitary Reversing Valve                                  

Applications The divert seat, valve is a kind of hygienicsingle-seat valve pneumatically ,which is applied to a wide range ofapplication in the food-processing industry, beverage production.pharmaceutical and fine chemicals industries.

Operating principle Seatvalves are operated automatically by a single-acting or a

double-actingpneumatic actuator. By supplying compressed air，the shaft is moved to place the valve in the "open" or"closed"position.

The180°rotation of the pneumatic cylinder of single-actingactuators allows to have a normally open or normally closed valve.

Design and features  Compact androbust design. 3A certified valve.

Availablesizes: from DN 25/1" to DN 100/4".

Normally closed valve (NC) in the standard version.

Thevalve can be changed to normally open (NO) by simply reversing the position ofthe pneumatic actuator.     Hygienicdesign according to 3A standards.    360°adjustable body.           Openlantern allows visual inspection of shaft sealing.    Easy assembly/disassembly of internal parts byloosening a clamp fastener.

Standardweld connections (mm or inches).
