In these applications, this type DCT16 Pressure Regulated Solenoid Control Valve ensures precise fluid control, maintains excellent sealing integrity, and supports efficient, safe operation even under demanding conditions.
The DCT16 Pressure Regulated Solenoid Control Valve is an advanced, multi-functional valve specifically engineered to perform automatic pressure reduction or regulation, with the capability of switching the pressure set point based on an electrical signal. Designed to meet the stringent demands of modern infrastructure, this specialized valve ensures precise hydraulic control, outstanding durability, and reliable automated adaptation to changing network requirements.
At the core of the DCT16 Pressure Regulated Solenoid Control Valve is its hydraulically-operated main valve controlled by a dual-pilot system (one pressure reducing pilot and one solenoid pilot). The pressure reducing pilot sets the default downstream pressure. When the solenoid pilot is electrically activated, it overrides the default pilot, causing the main valve to regulate to a secondary, pre-determined pressure set point.
Manufactured from high-strength, corrosion-resistant materials and built with a robust, globe-style body, the DCT16 Pressure Regulated Solenoid Control Valve is designed to withstand continuous system pressure and dynamic operational forces. The ability to remotely switch between two distinct pressure levels (e.g., high day pressure and low night pressure) significantly optimizes the distribution network, minimizing leaks and reducing pumping energy consumption.
The DCT16 Pressure Regulated Solenoid Control Valve is ideally suited for applications in District Metering Areas (DMAs), water transmission zones requiring time-based pressure changes, and any system where automated management of variable minimum night flow (MNF) pressure is essential for leakage control. Its superior adaptive characteristics and dependable operation make it a preferred choice for engineers seeking a high-integrity, standards-compliant solution for long-term network efficiency and conservation.
In summary, the DCT16 Pressure Regulated Solenoid Control Valve offers an optimal combination of pressure regulation, electrical automation, and flexible set-point switching. With its pilot-operated mechanism, dual-control system, and focus on adaptive management, this unit stands as a trusted solution for modern fluid control and smart network requirements worldwide.

Proper maintenance extends the service life of the DCT16 Pressure Regulated Solenoid Control Valve and ensures continuous, accurate dual-point pressure regulation. Follow the guidelines below to maximize the longevity of this essential unit.
1. Routine Operation
Visually inspect the DCT16 Pressure Regulated Solenoid Control Valve exterior, pilot line tubing, and electrical conduit regularly (e.g., monthly) for signs of external leakage, vibration, or corrosion.
Monitor the system pressure closely to confirm the valve maintains both the primary and secondary set points accurately upon electrical command.
2. Inspection Schedule
Monthly, check the pilot system strainers and filters for fouling and clean them to ensure accurate pressure sensing.
Quarterly, check the security of the solenoid coil and wiring connections; ensure the coil housing remains dry and undamaged.
Annually, perform a detailed internal inspection by removing the main cover to check the condition of the diaphragm, seating surface, and stem seals for wear or pitting.
3. Lubrication
The DCT16 Pressure Regulated Solenoid Control Valve utilizes fluid-lubricated internal parts (water).
External stem threads or guides (if applicable) may require periodic lubrication; use only recommended grease types.
4. Seal and Gasket Replacement
Replace the main cover/diaphragm gasket and pilot tubing seals immediately if external leakage is observed.
The main valve seat and disc seals should be replaced if pressure control fails (i.e., the valve leaks through or cannot maintain the set point).
Always isolate the valve and fully depressurize and drain the line before attempting any maintenance work requiring cover removal.
5. Cleaning
Keep the exterior of the DCT16 Pressure Regulated Solenoid Control Valve clean to prevent surface corrosion.
If the valve is disassembled, clean all internal guiding surfaces and the pilot line components carefully to ensure precision hydraulic response.

Why should I choose this product?
This valve delivers outstanding performance in both sealing and durability, making it a dependable choice for demanding applications. Its straightforward design facilitates easy installation, offering flexibility during system design. With a wide range of material options, it meets the needs of various infrastructure projects, from municipal water networks to industrial facilities.
What is the role of the solenoid in the DCT16 Pressure Regulated Solenoid Control Valve?
The solenoid acts as an override switch; it electrically commands the valve to switch from the high (default) pressure setting to the secondary low pressure setting (or vice versa), allowing automated pressure modulation based on flow demand or time of day.
How does the DCT16 Pressure Regulated Solenoid Control Valve optimize leakage control in DMAs?
By automatically switching to a lower pressure set point during periods of low consumption (typically night-time), the DCT16 Pressure Regulated Solenoid Control Valve significantly reduces the background leakage rate across the District Metered Area (DMA), conserving water.
How are the two pressure set points (High/Low) configured on the DCT16 Pressure Regulated Solenoid Control Valve?
The two set points are configured hydraulically using two distinct pilot valves (one for the high setting and one for the low setting). The solenoid simply selects which pilot valve is active and controls the main valve at any given time.
