衛生級截止閥（L閥） 衛生級換向截止閥 L-type sanitary stop valve

應用:該換向座閥是一種衛生級單座氣動操作閥門，在食品加工工業，飲料生產制藥和精細化工工業中有著廣泛的應用。

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

               單作用執行器的氣缸180度的旋轉，實現了閥門的常開和常閉型。

設計和特點

L-type sanitary stop 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).
