Weathermatic SilverBullet In-Line Valve with Flow Control 1" FPT

  • 1" Weathermatic 12024EF-10-H Valve
  • With Flow Control
  • 1" Female Threaded Inlet/ Outlet

Weathermatic Silver Bullet HP Valves feature superior materials, four-bolt covers, an unmatched manual bleed, a shock cone to reduce water hammer and a revolutionary reverse flow design which prevents valve failure in the open position. Excellent for micro-irrigation as valve will operate as low a 1 GPH. The unique "reverse flow" porting design permits equal pressure distribution on both sides of the diaphragm, regardless of line pressure providing zero stress to prevent "stretching," a common cause of valve failure.

Features & Benefits

    Superior Material

    • Glass-filled nylon construction gives the Silver Bullet added strength over conventional PVC valves.
    • Pick up a Silver Bullet in one hand and any other valve in the other to feel the difference.
    • S24BSA high efficiency solenoid

    Multi-Bolt Cover

    • Stainless steel bolts easily thread in and out of quality brass inserts.
    • Silver Bullet installers will tell you they rarely need to open a Weathermatic valve. When you do, it is easy to open and easier to close than most valves using screws or jar tops that are susceptible to stripping, dirt, and grit.

    Unmatched Manual Bleed

    • Send the Silver Bullet into action by simply pulling the trigger.
    • It's the easiest, driest internal manual bleed in the business that won't flood the valve box.
    • No twisting on a solenoid or bleed screw is required.

    Shock Cone

    • The Silver Bullet puts the hammer to water hammer by incorporating a cone-shaped diaphragm base.
    • The shock cone interrupts the water flow more gradually than other diaphragms to enable quick valve closure without the damaging effect of water hammer.

    Valve Identification System

    • Valve size and performance ratings
    • Zone number identification
    • Date code information
    • Bar coding

    Revolutionary Reverse-Flow Design

    • Reverse flow design means the valve fails shut rather than open in the event of diaphragm failure, unlike conventional forward flow valves that fail open.
    • Balanced pressure on the diaphragm extends valve life over forward flow valves.
    • Self-cleaning function is achieved as diaphragm actually flexes during operation to send dirt and debris down the line without the maintenance worry of filters and screens.

    Flow Control

    • Non-rising flow control stem throttles valve from full open to closed position on flow control models

Very good experience.
Overall I was pleased with my experience. Disappointed that my old value unit was discontinued and I couldn't purchase just the diaphragm.
Online purchase and delivery was fast and convenient.
Customer service was quick to respond the my email request.

Just what the "Doc" ordered
When I started to renovate the sprinkler system in this house I bought, I discovered I had a bad water hammering noise. I was skeptical at first and only ordered one valve at first. I installed it in the system where I was getting the worst water hammer. IT worked like a champ. I'm in the process of replacing all my valves with this unit. Just what the "Doc" ordered.

Weathermatic 21024E-10D-H 1 in. FPT In-Line Valve with Flow Control
Weathermatic 21024E-10D-H 1 in. FPT In-Line Valve with Flow Control
BEST ANSWER: The black one is built for dirty water. 21000 series valves.
What is the "off" position on the manual switch?
K R on Apr 25, 2012
BEST ANSWER: If you're referring to the "manual bypass valve" (the small piece on the outlet end of the valve) the "off position is the wing flat, twist the wing up, and water will come out - thus manual(ly) bypass(the)valve(solenoid). Hope this helps.
How can I tell if my existing valve have flow control or not?
A shopper on Sep 22, 2015
BEST ANSWER: Simply look to see if it has the black "X" shaped handle on top. If it does, then it has flow control.

Hope this helps!
What is the difference between the Weathermatic N-100-H and 12024EF-10-H valves?
Paul B on Oct 1, 2017
is valve threaded both ends - some pics show threads some do not ?
ogden h on Nov 19, 2017
BEST ANSWER: Yes, the ones I ordered had threads. I believe you can get them unthreaded as well. Just a different part number.
Do these valves really work at 1gph

Do these valves have to be level to work? Can they be mounted vertically and still work?
Ed M on Jul 9, 2013
BEST ANSWER: 1gph, heck they leak more than that! Don't see why you can't mount them vertically, most of them operate fully submerged anyway.
does this valve need a minimum pressure to operate?
tristan f on Jul 31, 2018
BEST ANSWER: don't know the answer to minimums. i get these for swimming pool auto fills and these have a higher pressure rating than the ones that come with the auto fill kit, therefore we buy our own solenoids. this brand and model has been more problem free than others i have used.
do you have 1/2 inch sprinkler control valves?
Michael B on Jan 17, 2017
BEST ANSWER: My use for these valves is different from most. I use them for automatic fillers for swimming pools and spas. I use a 1 inch to 1/2 inch PVC bushing. I have not noticed any problem with flow. The flow control allows for adjustment. Obviously you won't get as much flow from a 1/2 inch pipe as you would from 1 inch, but since you're already using 1/2 inch, you won't notice any difference. I have even bushed these valves down to 1/4 inch with no problems.
I have a solenoid valve M 24E weather matic, the main body is square. IT IS similar to the one yo have in the picture. What confuse me is the main body of my valve is square, but the one in your in your picture looks round?
A shopper on Jun 23, 2016
BEST ANSWER: what is the question? Will the one on the website fit your body? If so yes I bought the same one on the website for my square body valve and just replaced the top half of the valve. It worked fine.
Pam's Husband!
Can this valve be installed vertically?
A shopper on May 13, 2016
BEST ANSWER: You can try it I think it will work if that is how your setup is . The valve works great have had much success with it.
Weathermatic changed the body of the valve, bolt pattern and diaphragm are not the same as my valve.

Is the old style still available?
A shopper on Feb 25, 2020
BEST ANSWER: The silver bullet from Weathermatic was redesigned with a slightly new body design and a pressure activated diaphragm. The “old” one is no longer available unless if someone still has them left in their stock. I would recommend replacing with a complete new valve as the “new design diaphragms” will be what is available from here on out.
Will these valves be available again?
David S on Jun 11, 2017
Will these valves be available again?
David S on Jun 11, 2017
Why are they not available online?
A shopper on Jan 30, 2017
Is this valve available with a 120 volt ac coil?
Thank You!
Don Musick on May 23, 2014
I use these valves to feed only drip irrigation, I want to install a pressure reducer ( set at 25 psi ) in front of the valve box so only one will be needed. I can't find the operating pressure range for this valve, so the question is: is 25 psi supply pressure sufficient to close and keep it off when not in use?
