Gas Chromatography Solutions for Engineers

We help you get high performing and reliable valves for your Gas Chromatography solutions


Valve performance and reliability is critical to a high performing GC application

As an engineer, one of your largest challenges is to get your GC application and product out to market as quickly as possible.

  • Often, it can be difficult to find accurate information you need when searching online for valves to complete your GC application.
  • Lead time, product availability and warranty are crucial components when it comes to valve selection for your GC system.
  • Warranty and product reliability is important because there could be penalties if the overall GC solution you are building fails.

As an engineering company we understand the importance of meeting project deadlines while maintaining high product reliability and performance.

For over 18 years, we have built an industry leading R&D department to design the highest quality GC products to meet current and future requirements and invested in our production capacity to meet market demands.

Industry Leading High Performance Gas Chromatography Valves

Browse our complete family of Gas Chromatography Valves, including Diaphragm Valves, Rotary Valves, and Sample Stream Selection Valves, all engineered for today’s most demanding applications.


GC Injection & Switching Diaphragm Valves

AFP's GC Injection & Switching Diaphragm Valves are compact and performant with three different temperature grades, ambient to 100°C, 180°C, and 250°C.

Each Injection & Switching Diaphragm Valve is engineered with sealing integrity and optional purged valve features to ensure sample purity. Our patented GC diaphragm valves are designed with precise machined components, all made in-house with strict quality control. This creates a GC diaphragm valve with minimal opportunity for cross-port leaks for confident trace analysis.

GC Sampling & Switching Rotary Valve

AFP’s GC Sampling & Switching Rotary Valves are engineered to maximize efficiency. The rotary valve’s double stopper design increases the reliability and lifespan of the valve, which reduces maintenance and downtime.

Rotor options allow the valve to be used in any GC system with varying temperatures, covering applications from room temperature to maximum temperatures ranging from 225°C to 350°C. Coating options include advanced materials to combat corrosion and sulfur compounds absorption. Optional purged rotary valves ensure sample integrity for trace analysis.

Sample Stream Selection Diaphragm Valve

AFP’s GC Sample Stream Selection Diaphragm Valves offer individual port control, continuous flow path, and no dead volume effects for efficient, reliable sample stream selection in your GC analysis.

Purge features for the Sample Stream Selection Diaphragm Valves prevent any inboard contamination and ensure sample integrity. Other options include an electrical actuator, good for some portable GC or when actuation gas is not available, while keeping the same reliability.

For engineers, high quality products require high performing GC valves

As an engineer, delivering a quality product on time and on budget is your top priority. To achieve this, you need valves and other parts that are high performing and reliable to meet your project deadlines and produce a solution that is effective and long lasting.

AFP has the background and industry knowledge to meet these needs.

We are an engineering company with 18 years of experience developing high quality products that will meet any current and future project requirements.

Our solutions include Gas Chromatography valves with the highest quality materials to improve functionality, increase reliability, and ensure longevity.

AFP has also integrated innovative features into its Gas Chromatography Rotary Valves and Gas Chromatography Diaphragm Valves to make sure each valve reaches peak performance.

Features include a purge option embedded directly into the valve to prevent impurities from getting inside the system, removing the need for an additional purge box or other purging processes.

We also offer Dursan® and SilcoNert 2000® coated valves to combat corrosion and sulfur compounds absorption. Coated Valves come fully manufactured and tested with the coating to ensure maximum performance for accurate sample analysis.

AFP currently has 10 patented products, including our MRV-HT, Purged Rotary Valve and our MEA-I mini actuator. Our R&D team also has a roadmap of new products in different stages of development.

We are continuously looking for new ways to scale and grow our product line to meet the needs of the Gas Chromatography industry.
