Diaphragm Valve

Normally Open Diaphragm Valve (NO) (Standard)

Y52 series plastic diaphragm valve has 4 models.

Operating pressure: 1-8bar

Operating temperature: 4-50°C

Fatigue test: 100,000 times

Burst pressure test: ≥ 4 times of max. service pressure


Low pressure loss——Y-pattern designed plastic diaphragm valve, with large seat opening and high lift of disc part permits high flow rate at lower pressure loss.

Separate Diaphragm Chambers –Separate diaphragm chambers of control chamber and flow stream chamber, the design protects the diaphragm from the flow stream, enhances flexible operation. This allows the diaphragm to be replaced while the system is in service.

Long Diaphragm Life – Pre-formed, reinforced rubber diaphragm has high anti-fatigue strength, and long service life.

Corrosion Resistant – All internal parts in contact with media are made of composite materials.

Wide application —apply to a wide variety of water treatment system.

Valve is operated by either hydraulic or pneumatic pressure.



Valve Application:

Chemical Injection

Deionizers Desalinization

Fertilizer Spray Equipment

Process Water Systems

Water Treatment Systems

Level Control Systems

Detergent and Bleach Handling

Water Treatment Systems

Normally Closed Diaphragm Valve (NC)

Feature:

Closing valve: the pressure control source is connected with the upper control chamber, the diaphragm pushes the valve seat through the valve stem, thereby cutting off the water to close the valve.

Opening valve: the pressure control source is connected with the lower control chamber, the pressure in the upper and lower chambers of the diaphragm is balanced, and water pushes the valve stem through its own pressure, so that cavity is easily formed and water is passed.

Working pressure: 1-8bar

Working temperature: 4-50°C


Spring-Assist Closed Diaphragm Valve (SAC)

Feature:

A compression spring is mounted on the upper chamber of the diaphragm, and the valve seat is pushed downward by the spring tension to assist in closing the valve.

Working pressure: 1-8bar

Working temperature: 4-50°C


Spring-Assist Open Diaphragm Valve (SAO)

Feature:

A compression spring is mounted on the lower chamber of the diaphragm, and the spring seat is used to assist the valve seat to be upward, thereby assisting in opening the valve.

Working pressure: 1-8bar

Working temperature: 4-50°C


Limit Stop Diaphragm Valve (LS)

Feature:

By adjusting the height of the adjustment knob, the valve seat is opened to achieve the purpose of controlling the flow of water.

Working pressure: 1-8bar

Working temperature: 4-50°C

Position Indicator Diaphragm Valve (PI)

Feature:

When the valve is opened, the plunger is pushed upward by the valve piston, and only the rod is exposed, which indicates the opening of the valve.

When the valve is closed, the piston moves down. The indicator lever is reset by the return spring.

Working pressure: 1-8bar

Working temperature: 4-50°C



Signal Switch Diaphragm Valve (SS)

Feature:

Signal switch (normally open type): the control pressure source (the water source or air source pressure is equal to or greater than the inlet water pressure) connects to the upper control chamber of the diaphragm. When the upper chamber is pressurized (pressure is greater than 0.1MPa), the valve is closed, and the pressure switch is touched. The point is closed. When the upper chamber pressure is released, the valve opens and the pressure switch contacts open.

Signal switch (normally closed type): the control pressure source (the water source or air source pressure is equal to or greater than the incoming water pressure) connects to the control chamber of the diaphragm. When the upper chamber is pressurized (pressure is greater than 0.1MPa), the valve is closed, and the pressure switch is touched. The point is broken. When the upper pressure is released, the valve opens and the pressure switch contacts close.

Working pressure: 1-8bar

Working temperature: 4-50°C

Applicable voltageAC220V/110V/48VDC24V/12V

Max. power:100W24W

Max. Operating current: 500mA

Output form: dry contact

Switch form: normally open/normally closed

Solenoid Diaphragm Valve

Feature:

A solenoid valve is installed on the signal port of the bonnet, and the control of the pressure source signal is controlled by the power switch of the electromagnetic valve to achieve the purpose of controlling the diaphragm valve switch.

Working pressure: 1-8bar

Working temperature: 4-50°C

Liquid Level Control Diaphragm Valve (LLC)

Feature:

The adjustment knob of the diaphragm valve is controlled by a stainless steel ball valve to achieve the purpose of controlling the diaphragm valve switch.

Working pressure: 1-8bar

Working temperature: 4-50°C



Also known as two-position three-way valve, it has two models of 2” and 3”.

Working pressure: 1-8bar

Working temperature: 4-50°C

Made from reinforced polyamide (PA) material, sturdy and durable.

A special molding process is used to enhance the strength of rubber diaphragm and length of service life.

Grooved end connection for easy operation.

Simple structure, light weight and extremely low failure rate.
