WTA填料转换阀门类型11.7

概况

三方change-over-valve安全填料法兰设计按照EN 1092 - 1和ASME B 16.5分别;可以提供1.0619碳钢/ WCB,不锈钢1.4408 / CF8M、低温碳钢1.6220 / LCB LCC和特殊材料。

使用

使用转换阀允许必要的维护工作进行一个安全阀,没有中断的操作,只需改变相关的站在阀,从而保护植物免受过量超压。

植物是防止过度的过剩压力切换到相关的备用安全阀门。完整的排污能力时保持change-over-valve开关从一侧到另一侧。

当使用change-over-valves串联,手轮子都是通过链轮连接以保证同步操作。

设计特点

由于极低阻力系数*流偏转。账户的安全阀门可以组合与change-over-valveszui大程度相同的公称尺寸

控制重量紧凑施工方法

减少部分(例如,当安装安全阀)可以直接焊接上

WTA® Gland Packing Change-Over Valves Type 11.7 
概况

Three-way change-over-valve with safety gland packing in flange design in accordance with EN 1092-1 and ASME B 16.5 respectively; can be supplied in carbon steel 1.0619 / WCB, stainless steel 1.4408 / CF8M, low temperature carbon steel 1.6220 / LCB / LCC and special materials.

Use

The use of change-over valves allows essential maintenance work to be carried out on a safety valve, without interruption of the plant operation, simply by changing over to the relevant stand by valve, thus protecting the plant against excessiv overpressure.

Plants are protected against undue excess pressure by switching over to the relevant standby safety valves. Full blow off capacity is maintained when the change-over-valve switches over from one side to the other.

When using change-over-valves in tandem, both hand wheels are linked via a chain wheel in order to assure simultaneous operation.

Design features

Extremely low resistance coefficients due to optimal flow deflection. On account of this safety valves can be combined to the greatest extent with change-over-valves of the same nominal size 
Compact weight-saving construction method 
Reducing pieces (e.g. when mounting on safety valves) can be welded on directly
