Description

The Hunter Valve Diaphragm is a replacement diaphragm assembly for compatible 3/4 in. and 1 in. Hunter PGV and legacy SRV plastic valves. Retail part RTL1201332100 corresponds to Hunter diaphragm assembly 332100SP, the internal sealing component that opens and closes the valve as the solenoid changes pressure above the diaphragm. Replacing a worn, torn or debris-damaged diaphragm can restore reliable valve closing without removing the complete valve body from the irrigation piping.

Choose this repair part only after confirming the valve model and bonnet design. Official Hunter replacement-parts documentation lists 332100SP for PGV-100G, PGV-101G, PGV-ASV, PGV jar-top and compatible legacy SRV plastic valves. It is not a universal diaphragm for every Hunter valve and is not intended for 1-1/2 in. or 2 in. PGV valves. Before replacement, shut off the water supply and inspect the valve for debris, a damaged solenoid or cracked body because those problems will not be corrected by a new diaphragm alone.

I needed a replacement for my irrigation system and decided to go with the Hunter PGV. It was a perfect fit for my existing setup, making the installation process incredibly smooth and quick. The build quality is solid as expected from Hunter, and its been working flawlessly since I installed it. Highly recommended if youre looking for a reliable, easy-to-install valve.

Easy fix for a leaking sprinkler system.

Great replacement but inspect before installing

This is a perfect fit, reasonably priced replacement for your sprinkler system valves Easy to install. It would have been a 5 star product for me except that one of the units was torn right out of the box Didn't find out until I had installed it and took a while to.figure out what was causing a steady stream of water to the sprinkler heads even when the system was in the "Off" position

Replacement worked perfectly, installation was a bit challenging.

Good quality diaphragm for sprinkler valve, original manufactures equipment. It was a bit of a challenge to get down into the sprinkler well and remove the very tight screws from the valve. Of course, water leaked in from the sprinkler pipe and I had to clear that out as well as some debris that got into the valve. But, I did get the job done and it works great. No more leakage!

Frequently Asked Questions

Which Hunter valves does this replacement diaphragm fit?

It is compatible with specified Hunter PGV®, PGV-ASV, PRO-ASV and SRV configurations listed on the product page.

Can I repair a Hunter irrigation valve without replacing the entire valve?

In some cases, yes. If the valve body is still serviceable, replacing a worn diaphragm can restore proper operation.

Does the Hunter Valve Diaphragm fit every Hunter irrigation valve?

No. Confirm the exact valve model and size before ordering.

How do I know which replacement diaphragm my Hunter valve needs?

Identify the valve model and size, then compare them with the compatibility list on the replacement diaphragm product page.

Can replacing the diaphragm fix a valve that will not close properly?

A damaged or worn diaphragm can cause valve problems, so replacement may restore operation when the diaphragm is the cause and the remaining valve components are serviceable.
