Precision Flow-Adjustment Valves with Sanitary Quick-Clamp Fittings for Food and Beverage

To maintain sanitary standards in food, beverage, and dairy systems that require frequent cleaning, these valves are FDA compliant for direct food contact. Electropolished to a 20 Ra finish, they have smooth internal surfaces that prevent product buildup and inhibit bacteria growth. All have sanitary quick-clamp fittings for easy disassembly. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Valves have a 316L stainless steel body for excellent corrosion resistance. They have metal-to-metal seats that resist temperature fluctuations.

Air Pulse Valves for Filter Cleaning

Designed for use in dust-collection systems, these normally closed diaphragm valves periodically burst air to knock debris from filters. Connect the valve’s inlet port to your air supply, and connect the outlet port to the blow tube in your system.

Valves

Flow Coefficient (Cv)—Flow coefficient (Cv) is a measurement that indicates how much airflow a control valve can provide to your cylinder.

Severe-Duty Air-Driven On/Off Valves

Also known as diaphragm valves, these have a diaphragm that can handle dirty liquid, slurries, and abrasive media without damage. They operate on compressed air to automatically start and stop flow. You must control the air to the actuator using either an electric pilot valve (not included) or a manual on/off valve (not included). Valves don’t require a minimum pressure drop between the inlet and outlet for operation. All meet ANSI/FCI 70-2 Class IV for tight shutoff and have a leakage rate of less than 0.01%.

All valves have a single-acting actuator that only requires air pressure to actuate the valve; they automatically return to the valve starting position when the air turns off. The actuator is secured to the valve body with a bracket for easy disassembly, maintenance, and repair. These valves are fail closed unless actuated.

316 Stainless Steel Body—316 stainless steel valves are more corrosion resistant than bronze valves.

Compact Severe-Duty Air-Driven On/Off Valves

Less than half the height of standard severe-duty valves, these fit in small spaces and low-clearance pipelines. They have a diaphragm that can handle dirty liquid, slurries, and abrasive media without damage. All operate on compressed air to automatically start and stop flow. You must control the air to the actuator using either an electric pilot valve (not included) or a manual on/off valve (not included). Valves require a minimum pressure drop between the inlet and the outlet for operation; the upstream pressure must be greater than the downstream pressure.

All valves have a single-acting actuator that only requires air pressure to actuate the valve; they automatically return to the valve starting position when the air turns off. The actuator is directly mounted to the valve body to minimize movement and reduce wear.

Fail-Closed Valve—Fail closed valves are closed unless actuated.

Fail-Open Valve—Fail open valves are open unless actuated.

Severe-Duty Air-Driven On/Off Valves for Chemicals

Also known as diaphragm valves, these have a PTFE body and seals that stand up to harsh acidic solutions. The diaphragm can handle dirty liquid, slurries, and abrasive media without damage. All valves operate on compressed air to automatically start and stop flow. You must control the air to the actuator using either an electric pilot valve (not included) or a manual on/off valve (not included). These valves don’t require a minimum pressure drop between the inlet and outlet for operation.

All have a single-acting actuator that only requires air pressure to open the valve; they automatically spring closed when the air turns off. The actuator is directly mounted to the valve body to minimize movement and reduce wear. Valves are fail closed unless actuated.

Air-Operated Air On/Off Valves

Also known as blocking valves, these valves are activated by an air signal to turn equipment on and off. They allow airflow when an air signal is applied to the air pilot. When the air supply is removed, the valve closes, trapping air in the system.

Flow Coefficient (Cv)—Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.
