Hydraulic slow-close butterfly check valve is a pipeline of advanced control equipment, mainly installed in the water, electricity, to export pump drainage and other kinds of pumping station, replacing non-return valve and gate valve. When working, with the valve with the DCS system, through the design of the opening and closing process, effectively eliminate the pipeline water hammer, reliable implementation of stop line, to protect the pipeline system security role.
Product features:
■ can replace the water pump outlet of the original electric gate valve and check valve function, and the integration of machine, electricity, liquid system as a whole, reducing the occupied area and investment in infrastructure
■ electro-hydraulic control function is complete, no additional configuration that can be used as an independent system of single-machine on-site debugging, control; also can be used as a distributed control system (DCS) is an equipment unit, centralized management by the central computer through the I/O channel, and the water pump, and pipeline equipment to realize linkage operation; and is equipped with manual function, also can achieve manual open, close the valve without power supply, to meet the special conditions of the valve debugging, control requirements.
■ good controllability, wide regulation range, strong adaptability. The electro-hydraulic control system is provided with a plurality of adjustable nodes, can according to different pipeline control requirements to open and close the program settings, guaranteeing the open, close the valve when the valve condition, can automatically according to the preset time, angle to open and close, slow closing in two stages. And can realize the closed without electricity, effectively eliminate the destructive water hammer, to prevent the pump and turbine runaway accident, reduce the fluctuation of pressure pipeline system, guarantee the safe and reliable operation of equipment
■ optional drive mode: hammer, accumulator
■ main valve seal can be selection type: soft seal, seal
■ optional standard: GB, HG, SH, API, ANSI, ASME, AWWA, ISO, DIN, BS, JPI, JIS etc.
