Double gas valves for use on gas trains, consisting of 2 safety shutoff valves of class A. Suited for use in connection with gases of gas families I...III.
The double gas valve is to be combined with 2 actuators of the SKP… line (e.g. to provide the functions of 2 safety shutoff valves in series, with different types of gas pressure governor if required).
In combination with the appropriate SKP… actuators, the gas valve also serves as a:
-
Shutoff valve (in connection with the SKP10...)
-
Control valve with shutoff function (in connection with the SKP20..., SKP27..., SKP50... or SKP70...) | |
| 安裝 |
-
Ensure that the gaskets are fitted between the flanges
-
Check to ensure the bolts on the flanges are properly tightened
-
Check to ensure the connections with all components are tight | |

|
The double gas valves VGD40... are double seat disk valves of the normally closed type. The stems are guided on both sides of the disks, thus ensuring a precise stroke and tight shutoff. To improve the control performance, the disks at the bottom are profiled. The patented double seats are closed by 2 springs. The spring of each stem exerts a pressure on the disk so that there is a defined closing force acting on each disk. The surface area proportions of the 2 valve disks per stem are such that the closing force increases as the inlet pressure increases (class A valve to EN 161). A strainer on the inlet side protects the valve and downstream controls against dirt. The double gas valves DN65…150 correspond to the standard valve sizes of single valves (EN 558). | 型號表 |
