2000型法兰式角座阀flange angle seat valve (2000type)
优点(advantages):
外部先导角座阀,溢流口与滑块间有自调节密封压盖,阀体角座结构可实现较大流量,特别是与普通截止阀相比。
External pilot angle seat valve, overflow and the slider from the regulator gland, angle seat valve body structure can realize a large flow, especially compared with the general cut-off valve.
压力范围(pressure range):0-16bar
介质温度(medium temperature):-10℃~+220℃
环境温度(ambient temperature):-10℃~+80℃
阀体材料(valve body material):304或(or)316不锈钢(stainless steel)
密封材料(sealing material):聚四氟乙烯(PTFE)
执行机构外壳(actuator shell):聚酰胺(polyamide)
控制气体(The control of gas):中性气体(neutral gas),空气(air)
选取(select):
--控制功能(control function):常开(normally open)
--PPS执行机构外壳适用于环境温度(the shell of actuator applicable to environmental temperature)+5℃~+130℃
--弹簧单作用执行机构(spring single acting actuator)
--三夹式连接(three clip connection)
--电子式位置反馈(electronic position feedback)
--独立可调行程极限,适用高低流量(independent adjustable stroke limit, applicable to both high and low flow)
--手动应急开关(manual emergency switch)
--先导阀适用的Namur适配器(the Namur adapter for the pilot valve)
连接方法(connection method):法兰(flange)
