EMERSON-KEYSTONE 凯斯通F990/920蝶阀 KEYSTONE 基士敦F990/920是一个分体的阀体,薄阀板弹性阀座蝶阀设计的高流量和调节服务。这种阀门在需要耐腐蚀和耐磨的重型应用中非常出色。对夹式(图990)和支耳式(图920)。
详情介绍:

Keystone Figure 990/920 Butterfly Valve

The Keystone Figure 990/920 is a split body, thin disc resilient seated butterfly valve designed for high flow and modulating service. This valve excels in heavy duty applications where corrosion and abrasion resistance is required. It is available in both wafer (Figure 990) and lugged (Figure 920) style.

Features

One-piece, thin profile, disc stem provides minimum obstruction to flow, resulting in highest Cv, lowest pressure drops and best control characteristics.

Rounded polished disc edge gives full concentric sealing, lower torques, longer seat life and tight shut-off.

Triple function, resilient seat isolates body and stem from line media, provides drop-tight shut-off of line media at full-rated pressure and provides positive flange sealing, eliminating the need for flange gaskets.

Heavy duty, corrosion resistant top bushing provides upper stem support, absorbs actuator sideloading and extends valve cycle life.

Bi-directional, self-adjusting double V-cup stem seals prevent external contaminants from entering the valve.

Split body design enables easy field replacement of seat and disc/stem and permits direct mounting of Keystone actuators without the use of couplings or brackets.

特征

l  单件,薄剖面,阀瓣阀杆提供较小的阻力,导致较高的CV,较低的压降和较佳的控制特性。

l  圆形抛光阀瓣边缘提供**的同心密封,较低的扭矩,较长的阀座寿命和紧密的关闭。

l  三重功能,弹性阀座隔离阀体和阀杆与线材介质,在全额定压力下提供直线介质的降紧关闭,并提供正法兰密封,消除了法兰垫圈的需要。

l  重型,耐腐蚀顶部衬套提供上阀杆支持,吸收执行器旁和延长阀门循环寿命。

l  双向自调整双V型杯阀杆密封防止外部污染物进入阀门.

l  分离式阀体设计使阀座和阀瓣/阀杆的现场更换变得容易,并且不需要使用联轴器或托架就可以直接安装Keystone执行器。
