1.5 Inch Stainless Steel Check Valve Solution for Pharmaceutical Chemical Transfer Systems

CVS Check Valve Provides Reliable Flow Control for DMSO and DMAC Applications

In pharmaceutical manufacturing and process equipment, reliable fluid control is essential for maintaining stable production conditions.

When handling chemical solvents such as Dimethyl Sulfoxide (DMSO) and Dimethylacetamide (DMAC), the selection of suitable valves requires careful consideration of material compatibility, sealing performance, and pressure control.

For one pharmaceutical industry customer, the existing challenge was finding a 1.5 inch check valve that could meet both the system size requirements and specific cracking pressure requirements.

After reviewing the application conditions, CJan Fluid Technology Co., Ltd. provided the CVS stainless steel check valve solution, designed for chemical fluid transfer applications requiring reliable one-way flow control.


Customer Background

The customer operates in the pharmaceutical industry and provides equipment and process solutions related to pharmaceutical production.

During the manufacturing process, chemical liquid transfer systems require check valves to:

  • Prevent reverse flow
  • Protect upstream equipment
  • Maintain stable process operation

The application involved transferring two chemical solutions:

  • Dimethyl Sulfoxide (DMSO)
  • Dimethylacetamide (DMAC)

Application Requirements

Industry

  • Pharmaceutical manufacturing
  • Chemical process equipment

Medium

  • DMSO (Dimethyl Sulfoxide)
  • DMAC (Dimethylacetamide)

Operating Conditions

Temperature:

  • Ambient temperature

Valve Size:

  • 1.5 inch

Cracking Pressure Requirements:

  • 1 psi
  • 25 psi

Customer Expectations

The customer required:

  • A large-size check valve solution
  • Reliable chemical compatibility
  • Stable opening pressure
  • Long-term operational reliability

Application Challenge

Limited Availability of Large-Size Check Valves

During the initial product search, the customer found that many standard check valves available on the market were limited to sizes up to 1 inch.

For a 1.5 inch piping system, this created several challenges:

  • Additional reducers or adapters were required
  • Increased installation complexity
  • Potential impact on flow performance

A properly sized check valve was needed to simplify system integration.


Chemical Compatibility with Organic Solvents

DMSO and DMAC are commonly used organic solvents in industrial and pharmaceutical applications.

Valve materials must provide:

  • Good chemical resistance
  • Stable sealing performance
  • Resistance to long-term exposure

Material selection is especially important in pharmaceutical process systems where reliability and cleanliness are required.


Recommended Solution: CVS Stainless Steel Check Valve

Based on the customer's operating conditions, CJan Fluid Technology Co., Ltd. recommended:

CVS Stainless Steel Check Valve

The CVS series is designed for industrial fluid control applications requiring reliable one-way flow protection.

The solution was selected based on:

  • Valve size requirements
  • Chemical compatibility
  • Opening pressure requirements
  • Application environment

Advantages of CVS Check Valve

Available for Large Diameter Applications

Compared with many standard check valve products, the CVS series supports larger piping applications.

This helps:

  • Reduce unnecessary pipe transitions
  • Simplify equipment design
  • Improve installation efficiency

Precise Cracking Pressure Selection

The application required two different opening pressure specifications:

  • 1 psi
  • 25 psi

CVS check valves can be configured according to different process requirements, helping maintain stable fluid control.


Suitable for Chemical Fluid Transfer

The stainless steel construction provides reliable performance in applications involving:

  • Organic solvents
  • Chemical solutions
  • Pharmaceutical process fluids

Reliable Backflow Prevention

The primary function of a check valve is preventing unwanted reverse flow.

CVS helps protect:

  • Pumps
  • Process equipment
  • Fluid systems

while maintaining stable operation.


Application Result

After evaluating the customer's requirements, CJan Fluid Technology Co., Ltd. supplied the CVS stainless steel check valve solution.

The final solution addressed the key challenges:

  • 1.5 inch valve size requirement
  • DMSO and DMAC chemical transfer
  • Ambient temperature operation
  • 1 psi and 25 psi cracking pressure requirements

The CVS check valve provided a reliable option for pharmaceutical chemical transfer systems where standard valve sizes could not meet the application requirements.
