21型氣動換向閥（L型） L-type Sanitary Reversing Valve

應(yīng)用:該換向座閥是一種衛(wèi)生級單座氣動操作閥門，在食品加工工業(yè)，飲料生產(chǎn)制藥和精細(xì)化工工業(yè)中有著廣泛的應(yīng)用。

操作原理該座閥由單作用或雙作用的氣動執(zhí)行器自動操作。壓縮空氣推動軸來定位閥門開或關(guān)的位置。

單作用執(zhí)行器的氣缸180度的旋轉(zhuǎn)，實現(xiàn)了閥門的常開和常閉型。

設(shè)計和特點閥體采用國內(nèi)鍛壓設(shè)計

尺寸從DN25/1“到DN100/4"   標(biāo)準(zhǔn)為常閉型閥門(NC)

通過簡單的改變氣動執(zhí)行器的活塞，閥門就可以轉(zhuǎn)變成常開型(NO) 根據(jù)3A 標(biāo)準(zhǔn)衛(wèi)生設(shè)計  360度可調(diào)節(jié)外部結(jié)構(gòu)  開啟的窗口用于觀看檢查軸密封情況通過松開卡箍，就可以簡單的拆卸內(nèi)部部件    焊接式連接口(毫米或英寸)

L-type 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).
