What is a Saunders valve?

The Saunders® Industrial Diaphragm Valves, first developed more than seventy years ago, have evolved to handle more fluids, gases, solids, and powder than any other type of valve.

What is a weir valve?

Weir Valves A weir valve is a type of diaphragm valve in which the flow passage includes a weir, or a notch with a horizontal edge through which a substance flows. In the open position, the diaphragm lifts up and allows a substance to flow freely through the valve.

What is aseptic diaphragm valves?

The NDL (Non Dead Leg T Valve) diaphragm valves, manually or pneumatically operated, are specially designed for use on aseptic processes in the pharmaceutical industry. The valves are widely used at points of use in the loops of purified water (PW) or water for injections (WFI).

How does a pneumatic diaphragm valve work?

The most common diaphragm valves use pneumatic actuators; in this type of valve, air pressure is applied through a pilot valve into the actuator which in turn raises the diaphragm and opens the valve. This type of valve is one of the more common valves used in operations where valve speed is a necessity.

What does a plug valve do?

Usually available in cylindrical or conical shapes, plug valves are quarter-turn manual motion valves used for stopping or starting the flow of fluid. They offer on-off, diverting, as well as basic moderate throttling services.

What is a weir gate?

Weir Gates are designed to control upstream water elevation and can provide a rough estimate of flow using notched gates via the downward- opening design. Weir gates function like slide gates, except that the disc opens downward allowing outflow to weir over the top of the gate.

How does automatic weir valve work?

The Auto Flo Weir Valve works by regulating the flow through the pool cleaner to the pump. As the filter collects debris, the valve will automatically maintain the correct flow.

What are diaphragm valves used for?

In simple terms, the main purpose of a diaphragm solenoid valve is to control the flow of liquids and gases. Diaphragm solenoid valves have a rubber diaphragm that moves up and down within the body of the valve, causing opening and closing against a hard seat.

What is diaphragm type?

Diaphragm and bellows type are commonly used pressure sensors that give responses related to the pressure. The diaphragm type consists of a thin disc of metal or plastic, secured round its edges. When there is a pressure difference between the two sides of the diaphragm, the center of the diaphragm deflects.

What type of valve is a diaphragm valve?

Diaphragm valves are bi-directional, on-off throttle valves. They are used to control fluid flow by regulating the area with which media can enter and exit the valve, effectively changing its speed and velocity.

What does a ball valve do?

Ball valves use a metal ball with a hole bored through the center, sandwiched between two seats to control flow. Used in many hydrocarbon process applications, ball valves are capable of throttling gases and vapors and are especially useful for low flow situations.

Saunders A type: the valve of choice to handle highly corrosive media Original Saunders Design 10 wwwcranecpecom Our metal bodies provide simultaneous mechanical support for the lining and a protection for the lining against Ultraviolet (UV) attack.

Why choose Saunders a type diaphragm valves?

What is a weir type diaphragm valve used for?

A specialised range of weir type diaphragm valves for marine and firefighting applications. Used primarily as water hydrant valves because of 100% reliability in adverse conditions. DN40 and DN65 AFP valve

What is the Saunders® I-Vue?

The Saunders® I-VUE is a compact intelligent valve sensor that provides accurate and reliable valve position feedback. It is suitable for EC or ECX actuated valves.
