Inquiry (采购产品): AVAILABILITY OF VALVES ATTN: SALES DEPARTMENT We are fabricating and installing filter housings and would require a 3 way valve for the following. We would require the valve complete with electrically actuated control to direct flow from 1 port to another for the following function. INSTALLATION / OPERATING REQUIREMENT: We need a 3 way valve to be installed with 2 units of Filter Housings and the outlet of these housing will be connected to a manifold. One of these filters will be on stand-by (with the port to this filter housing inlet closed) while the other filter housing will be running with the valve opened. Over time, the operating unit will get choked up and will have a pressure build up on the inlet end of this operating filter housing. We need a sensor to trigger switch over of the 2 way valve upon pressure build up to the stand-by filter housing to re-direct flow and vice versa. This is to ensure a continuous flow. We would need the following items for this system and if your company do supply any or all that we would need, would appreciate if you could give us a quote and send brosure either via mail or via e-mail. 1] Sensor as describe above. 2] 3 way valves, Size :: 4" on all 3 ports with ANSI 150# flange connection. Size - 6" on all 3 ports with ANSI 150# flange connection. Please note that the fluid will be EXXOL and all seals are to be of VITON material. Valve casing can be of any material suitable for EXXOL fluid. Would appreciate your advise on the above as soon as possible. Best Regards Victor Ng Graceland Discovery Pte.
