600X Electric Hydraulic Control Valve – Pilot-Operated Hydraulic Valve with Electromagnetic Remote Control for High-Rise & Municipal Water Networks

The Coliter® 600X Electric Hydraulic Control Valve is a pilot-operated, remotely controlled valve designed for reliable on/off control in large-scale water supply systems such as high-rise buildings, residential complexes, and urban water distribution networks. It combines hydraulic efficiency with electrical convenience: while the main valve is actuated by system pressure (requiring no external power), remote opening and closing are achieved via a low-power solenoid pilot valve, significantly reducing energy consumption compared to conventional electric actuators. The valve assembly includes a main valve, electromagnetic pilot valve, needle valve, ball valve, micro filter, and pressure gauges. During operation, inlet water flows through the needle valve into the main valve’s control chamber. When the solenoid pilot opens, water drains from the chamber faster than it enters—dropping pressure and causing the main valve to open fully. When the solenoid closes, the chamber pressurizes, pushing the diaphragm to shut the main valve. Optional accessories allow adjustment of opening/closing speed to prevent water hammer. Constructed from ductile iron or cast steel, rated at PN16 (1.6 MPa), and suitable for media temperatures up to 80°C, it handles clean water only. Available in sizes from DN20 to DN800 with flanged ends per GB/T 17241.6. By leveraging system hydraulics for actuation and electricity only for signaling, the 600X delivers energy-efficient, fail-safe, and scalable remote control—ideal for smart water infrastructure.

Product Description

600X hydraulic electric control valve consists of main valve, solenoid pilot valve, needle valve, ball valve, micro filter and pressure gauge to form a hydraulic control takeover system. The remote control of the valve opening and closing can be realized through the solenoid pilot valve. The speed of opening and closing can be controlled by adding additional devices. When the valve feeds water from the inlet, the water flows through the needle valve and enters the main valve control room. When the solenoid pilot valve is opened, the water in the control room flows out through the solenoid pilot valve and ball valve. It can replace other large-scale electric devices of valves and is widely used in high-rise buildings, living areas and other water supply pipe network systems and urban water supply projects.

Faq - Frequent questions

Coliter®’s hydraulic control valves are pilot-operated, multi-function automatic valves designed for intelligent water system management in high-rise buildings, fire protection, and municipal networks. The series includes the 600X electric hydraulic control valve (remote on/off via solenoid), 500X pressure relief/pressure reducing valve, 400X flow control valve, 300X slow-closing check valve, 200X pressure sustaining valve, and the LHS743X low-resistance backflow preventer. All models use system pressure as the driving force—requiring no external power—and feature brass or ductile iron bodies, Y-strainer integration, and precise pilot control for stable operation. Rated at PN16 (1.6 MPa) and suitable for temperatures up to 80°C, they ensure safe, energy-efficient, and code-compliant water distribution with automatic response to demand changes.
