WSP Reverse Osmosis Valve Head - VH-1600G

If you have a reverse osmosis system, the control head assembly is the part that manages the flow and timing of water through the membranes. The WSP Reverse Osmosis Valve Head - VH-1600G is a replacement valve head designed to fit a range of RO systems from small to very large capacities, helping keep your water treatment running smoothly.

The problem

Your reverse osmosis system depends on a control valve to direct water through the different stages of filtration. When that valve head wears out or malfunctions, you may notice your system runs inefficiently, produces less clean water, or even stops cycling properly. Without a working valve head, the whole purification process gets disrupted, and your filtered water supply suffers.

Why it’s happening

The valve head is a mechanical control assembly that regulates when and how water flows through the membranes and rinses the system. Over time, the internal seals and moving parts inside the valve head can degrade, especially if your water has minerals or sediments that cause abrasion. A common way to confirm you need a new valve head is if your system’s flow rates drop or the cleaning cycles no longer run on schedule.

What it’s costing you to leave it

If the valve head isn’t working correctly, your membranes may foul faster, reducing water quality and system output. The system could waste water during rinse cycles or fail to flush contaminants properly, leading to more frequent membrane replacements and higher ongoing costs. You may also end up with less filtered water at peak demand times, affecting drinking water availability.

How this system fixes it

This valve head replaces your existing control assembly, managing the flow of water through your reverse osmosis membranes with precision. It uses a series of timed cycles to direct untreated water through the membranes, wash away contaminants during rinse phases, and deliver filtered water efficiently. By restoring the valve head’s function, it helps your system run as designed.

What this system can handle

The VH-1600G valve head is offered in four sizes: from 1600 gallons per day (GPD) up to 20,000 GPD, covering a wide range of residential and commercial RO systems. Whether your demand is for a modest household or a larger facility, there’s a valve head sized to match. Each version controls the purification cycles for its capacity, ensuring smooth operation without frequent interruptions or overloads.

What you actually get

You receive the complete control valve head assembly, designed for direct replacement in compatible reverse osmosis systems. The exact setup depends on the size selected, but all versions provide the core timing and flow control functions needed to operate your RO membranes efficiently. Detailed installation and operating manuals come with your order to assist your plumber.

Is this the right size for you

If your system’s daily water demand falls within the range of 1,600 to 20,000 gallons, choosing the valve head sized closest to your capacity is best. A smaller valve head won’t keep up with higher flows, risking performance issues. Conversely, a valve head that’s too large may cycle inefficiently at low demands. Contact us with details of your system’s current output or intended use, and we’ll help you select the best fit.

Living with it

Once installed by your licensed plumber, the valve head requires no special maintenance beyond your normal system upkeep. Regular membrane cleaning and timely filter changes will keep the system running well. The valve head is built for durability but, like all moving parts, may eventually need replacement after several years depending on water conditions.

What it won’t do

This valve head is a control assembly only — it does not include membranes, filters, or pumps. It won’t improve water quality on its own or address issues like hardness, iron, or sulfur. If you have those problems, you’ll need separate treatment before the RO system. Also, this valve head does not include bypass valves or discharge hoses.
