PULSAtron L3201TC3-PVC Discharge Valve Assembly

The PULSAtron L3201TC3-PVC is a discharge valve assembly used on compatible PULSAtron chemical metering pumps equipped with VTC3 and WTC3 wet-end configurations. The valve installs on the discharge side of the pump head and helps maintain one-direction chemical flow during operation.

Pulsafeeder parts documentation specifically identifies L3201TC3-PVC as the discharge valve for the VTC3 wet end. The assembly uses PVC construction, PTFE/Teflon sealing components, ceramic valve components and a 1/2-inch OD tubing connection.

L3201TC3-PVC Product Configuration

• Part Number: L3201TC3-PVC
• Product Type: Discharge Valve Assembly
• Product Family: PULSAtron
• Wet-End Compatibility: VTC3 & WTC3
• Body Material: PVC
• Sealing Material: PTFE / Teflon
• Valve Component Material: Ceramic
• Connection: 1/2-Inch OD Tubing

Discharge-Side Check Valve

The L3201TC3-PVC mounts on the upper discharge side of the compatible metering pump head. Its purpose is to control chemical flow as the diaphragm alternates between suction and discharge strokes.

During the discharge stroke, pressure generated inside the pump head allows chemical to move through the discharge valve and into the discharge tubing. During the opposite portion of the pumping cycle, the check-valve arrangement helps restrict reverse flow.

PVC, PTFE & Ceramic Construction

The valve uses a PVC body together with PTFE/Teflon sealing components and ceramic valve components. This material combination is associated with compatible VTC3 and WTC3 PULSAtron wet ends.

Chemical compatibility should always be verified for the actual process chemical, concentration, temperature and operating conditions before installation.

Connection Details

The L3201TC3-PVC is configured for a 1/2-inch OD tubing connection. The discharge tubing connects to the valve fitting and is secured using the applicable connection hardware.

Connection size should be verified before replacement because PULSAtron liquid ends are available with several different tubing and fitting configurations.

VTC3 & WTC3 Wet-End Applications

PULSAtron parts documentation identifies L3201TC3-PVC for VTC3 wet ends, while current replacement-parts documentation also identifies it for compatible WTC3 configurations.

Examples of pump configurations using this discharge valve include compatible size 4, 5 and 6 VTC3 wet ends as well as selected size 7 WTC3 configurations.

Related Liquid-End Components

The L3201TC3-PVC works as part of a complete PULSAtron liquid-end system. Related components documented for VTC3/WTC3 configurations include:

• L3101TC3-PVC – Suction Valve Assembly
• L3201TC3-PVC – Discharge Valve Assembly
• L3300T03-PVC – Bleed Valve Assembly
• J60728 – Foot Valve / Strainer Assembly
• J41873 – Injection Valve Assembly

Role in Chemical Metering

A properly functioning discharge check valve is important for consistent chemical delivery. The valve must open during discharge and seat correctly during the opposite portion of the pumping cycle.

Deposits, worn sealing surfaces or damaged valve components can interfere with proper seating and may contribute to reduced output, difficulty priming or inconsistent metering performance.

When to Inspect the Discharge Valve

• Pump has difficulty maintaining prime
• Chemical output becomes inconsistent
• Flow appears to reverse toward the pump head
• Deposits are visible around valve components
• Valve components show wear or chemical deterioration
• Liquid-end components are being serviced as part of preventive maintenance

Selection & Installation Note

Confirm that the pump uses a compatible VTC3 or WTC3 wet-end configuration and requires a 1/2-inch OD tubing connection before installing the L3201TC3-PVC.

The L3201TC3-PVC is the discharge valve. For the corresponding suction-side component, use the appropriate suction valve specified for the pump configuration, such as L3101TC3-PVC for documented VTC3/WTC3 applications.
