Does this timer have a diaphragm or ball valve?

The Claber 8454 has a diaphragm.When it switches between open and closed it clicks.

Have used this timer for almost a year without missing a beat. Replaced batteries once in a year. The operation is flawless. It sounds like a screw drive opening and closing so believe it is a ball valve. Contact customer service if it is that important to you. Whatever it is, it works like a dream.

You could call "For customer service contact: Claber, Inc. 800-930-4566 or info@claberinc.com" and ask which it is. It states "Reliable solenoid valve designed for smooth water shut off that prevents water hammer impact." I assume it would be a ball type valve to handle these specs "Functions with operating pressure as low as 1.45psi up to 174psi." And it has a pretty robust clicking action when using manual mode or when it turns on for the cycle. Mine worked excellent and had one of the best garden in years, best purchase of 2013 for me. If you are looking for a 2 time a day watering cycle, this thing is awesome. Update 7/15/2014: Second year using it and it is perfect, as one reviewer mentioned to use a fresh battery every season and it is chugging along as expected totally recommended.

It is the complete valve and timer you should have a bypass valve going into the back of the control

I did not need one. My problem with the timer was that it did not work, so I trashed it. Unfortunately, I had failed to keep the box it came in and my receipt, so I couldn't return it, yet I'd be thrilled if Amazon sends me a refund anyway. Later, I found one that does work. It's made by GE, and I bought it at Target.

Yes, it has two timers, each can be used to control a motor (the filtration pump and the cleaner pump).

yes there is a valve in all of the hose ends and the extension.this tester does not allow you to add any volume of air to the cylinder due to the one way valve design.test is only used to allow air from cylinder into tester.

No.....both valves work together.. on or off.........the 3 valve unit has a separate manual valve that can be left on, but is NOT controlled by the timer.

Nathaniel Allen already fielded your question in his fine review of the product. Quick answer...no, it's a mechanical water timer. You'll need to step up to one of the battery-powdered digital devices sold on Amazon.

Mine is a diaphragm type. But it makes no difference as I dive only in tropical waters at depths no more than 50 meters.

No,it does not. I just bought a separate Intermatic TN311 15 Amp Heavy Duty Grounded Timer also off Amazon.

I'm sorry. I don't know if it does. I don't have these automatic timers anymore, sold them with the home I left them with. Sorry I can't answer your question. I set timers for a certain time but not like your times. They worked well for me. Sorry I can't answer your question. :o/

No, but it does have a lip/groove that seals out the water and salt. I've had two pool timers like this forsixteen years and recently converted to the digital timer in one box, controlling the main motor at two speedsand the polaris cleaner on a separate circuit. As these sturdy boxes age, you can buy an inexpensive insertthat replaces the tabs inside for many more years of service. Great quality from a great company.

Sorry, can't remember. It is at our house in AZ. I just know it is a great timer.

The timer is an "on/off" device. It operates on time, not flow volume. It can be set on, without timing, or on for up to 120 minutes.

It has a pressure release valve, and I find that it cools down quickly, but I've never actually timed it.

It uses a spring loaded valve with what might be called an egg timer. When the timer counts down to zero the valve shuts. There is no external power required.

Probably 3V DC since the Orbitz timer uses 2 batteries. The valve probably has a DC motor that runs briefly to open or close the valve by changing the +/- polarity of the voltage applied to the valve.

Myron, it must have a small dedicated return line with a check valve if you are using the model with the timer
