Advantages Of Sanitary Pneumatic Tank Bottom Valve With Sampling Valve

A sanitary tank bottom valve with integrated sampling valve combines tank draining and sterile sampling in a single body. The main valve mounts flush to the tank bottom with zero dead-leg design. The sampling valve attaches to the side outlet for representative sample extraction. This integrated design eliminates separate sampling ports, reducing piping complexity and contamination points in pharmaceutical, biotech, and food processing.

How does a tank bottom valve with sampling valve work

1. The main diaphragm valve opens to drain product through the bottom outlet.

2. The sampling valve opens independently to extract a representative sample.

3. Both valves operate manually or pneumatically for automated control.

4. The integrated design allows CIP/SIP cleaning without disassembly.

Common Application Pitfalls

• ❌ Separate sampling port installations → Specify integrated sampling valve on the tank bottom valve body.

• 📉 Dead legs in tank outlet → Specify zero dead-leg flush-mount design.

• 🔍 Incompatible cleaning of sampling valve → Specify integrated CIP/SIP capability.

• ⚡ Wrong valve type for tank bottom service → Specify diaphragm-type for zero dead-leg.

Two-in-One Design – Simplifies Piping

The main valve body mounts flush to the tank outlet. A sampling valve integrates into the side port, creating a single assembly that performs both functions.

Benefits:

• Reduces piping complexity and installation cost

• Eliminates additional tank penetrations

• Minimizes contamination points

• Enables simultaneous CIP/SIP

A tank bottom diaphragm valve with integrated sampling port provides complete drainability while enabling representative sampling.

Zero Dead-Leg Flush-Mount Design

The main valve mounts directly to the tank bottom flange with the diaphragm sealing flush to the tank floor, eliminating the traditional "pocket" at the tank outlet.

Key design features:

• Flush-mount with no pipe extension below tank

• 30° or 45° angled outlet for gravity drainability

• Internal surface finish Ra ≤ 0.4 μm

• Self-draining geometry with no horizontal pockets

Sampling Valve Integration

The sampling valve mounts on the side outlet. It operates independently, allowing samples without opening the main drain valve.

Features:

• Independent operation from main valve

• Small volume for representative sampling

• Sterilizable with steam or SIP cycles

• Manual or pneumatic versions

Specifications

Configuration Guide

A sanitary tank bottom valve with integrated sampling valve combines draining and sampling in one assembly, reducing piping complexity and contamination points. 316L with electropolished finish (Ra ≤ 0.4 μm) prevents bacterial adhesion. EPDM+PTFE diaphragms withstand SIP to 150°C. A tank bottom diaphragm valve with integrated sampling port provides complete drainability while enabling representative sampling without additional piping.

Intelligent Pneumatic Aseptic Tank Bottom Valve With Sampling Valve

• The aseptic tank bottom valve is a valve with a diaphragm sealing structure, cleanliness and durability. The seal is made of Japanese Daikin materail, which ensures usability and durability to a greater extent. The valve body is forged from SS316L round steel and precision machined by CNC. The inner roughness can reach Ra≤0.4μm.
• The outlet of the valve body is lower than the sealing plane, allowing the material to be completely evacuated.
• Supports online and offline sterilization.
