Penstock valve type, ROAS fade has more size, used in regulating the system of water supply and water treatment.
The frame is designed to have checked valves, control the speed up and down the gate, from which regulate the water flow through the door of the van. All gates are manually operated through the need to rotate the controls, but also easily add more electric, pneumatic or hydraulic cylinder.
Sliding plate: stainless steel 316 l
Frame: 316 l stainless steel valves with HDPE led strips
Fixed shaft seal: EPDM
The axis line: POM
And other stuffs.
The principle of operation
Effect of gate valve to regulate the water level is fading, can increase or decrease the water level went through the door by sliding plate level. The water flows through the sliding panels will be moderated. Against spills and keep the water level in certain levels.
The type of gate valve fade type I type II ROAS & ROAS
Currently there are two types of products gate valve consisting of a main shaft I ROAS fade & ROAS II dual axis.
The use of single or dual axis axis depends on the width of the frame, slide valve. When the frame width 1500 mm from the valve back down then just taking the van door fading single axis is enough. Conversely when the van door frame width greater than 1500mm, then fade should use the van door dual axis fade.
+ Width: 20 mm t/m 5000mm
+ Height: 100 mm t/m 3000mm
Control method: by hand or by means of active point control: electric, pneumatic or hydraulic cylinders.
