I would like to request your best pricing and estimated delivery time for a pneumatic positioner device. We need a total of 10 units designed for double-acting pneumatic actuators, specifically for a 500mm diameter butterfly valve. The positioner should have four air ports: one for main air supply, one for control air, and two for actuator connections for opening and closing. It must operate at a maximum air pressure of 6 bar and control air pressure should not exceed 2 bar. Additionally, it requires a 6mm diameter for the actuator's air hoses, an indicator for valve status (open/closed percentage), and gauges for main, control, and operating air pressure. The device should meet an Ingress Protection rating of at least IP66 and come with a mounting kit for the valve actuator. Looking forward to your prompt response!
