Silicone Valves By Function

Surgical Valves

  • Trocar valves
  • Access valves
  • Other surgical applications

Trocar Valves

Trocars valves maintain a controlled environment by preventing gas and fluid leakage. These valves enable precise instrument insertion, reduce infection risk, and enhance surgical efficiency, making them indispensable in minimally invasive surgeries. 

We offer:

  • 1st (for the primary instrument) and 2nd (for insufflation) trocar valves;
  • Standard valves for 5 mm, 10 mm and 12 mm trocars;
  • Valve housing drawings are available upon request at no cost;
  • Offer of universal valves, compatible with various instrument diameters and geometry;
  • Ensuring safety and peace of mind for both patients and healthcare technicians during administration, reducing risks.

Access Valves

When performing some medical procedures, it is necessary to the insertion of pressurized fluid for various purposes. For instance, pressurized carbon dioxide gas is often used to inflate the abdomen, creating space for the surgeon to work and improving visibility.

Using a valve for surgical access offers several advantages:

  • Maintaining Pneumoperitoneum: In laparoscopic or minimally invasive surgeries, a pneumoperitoneum (a space filled with carbon dioxide gas) is created to provide better visibility and working space inside the abdomen. Valves help maintain this pneumoperitoneum by preventing gas leakage when instruments are inserted or removed through the trocar port;
  • Reduced Risk of Contamination and Infection;
  • Smooth Instrumentation: Valves provide a smooth passage for surgical instruments, to be inserted and manipulated within the abdominal cavity. This allows for precise and controlled movements during surgery;
  • Minimized Air Leakage;
  • Improved Surgical Efficiency: The use of valves for instrument access streamlines the surgical process by facilitating easy instrument exchange and reducing the need for repeated insufflation of gas into the abdominal cavity;
  • Enhanced Patient Safety: By minimizing gas leakage and reducing the risk of contamination, valves contribute to enhanced patient safety during minimally invasive surgeries.

Other Surgical Applications

Valves in surgical applications are versatile components, integral to maintaining precision and safety in a range of procedures. Found in endoscopic, laparoscopic, cardiac, and numerous other surgeries, these valves seal tightly to prevent gas and fluid leakage. Their unwavering reliability and performance are critical for patient safety and optimal surgical outcomes

We offer:

  • We offer a wide range of valves, including standard options like cross slit, dome, duckbill, and others. Whether you choose from our standard valves or opt for custom designs, our valves are suitable for a diverse range of surgical applications, meeting your specific needs and quality standards.

Non-Surgical Valves

  • Check Valves
  • Valves for: IV sets; IV sets, Enteral/Parenteral feeding, Medical diagnostics, Drainage systems
  • Other non-surgical applications

Check Valves

Check valves allow the flow of fluids in one direction while preventing backflow. In surgical contexts, they play a crucial role in maintaining precise fluid management during procedures such as cardiopulmonary bypass, hemodialysis, and infusion systems.

We offer:

  • Components for: barbed, one-way, high-flow, anti-siphon and other check valves;
  • Support and ease of modifying valve
    designs, addressing different pressures
    and materials

Valves for: IV sets; IV sets, Enteral/Parenteral feeding, Medical diagnostics, Drainage systems

1.IV Sets

Intravenous (IV) devices represent one of the primary applications for our valves, with IV sets being ubiquitous in hospitals worldwide. Incorporating our valves into IV sets offers several advantages:

  • Flow Control and Backflow Prevention;
  • Intermittent Infusions: Valves allow healthcare providers to pause or stop the infusion temporarily without disconnecting the IV line.
  • Minimizing Air Embolisms;
  • Reducing Waste: Valves enable more efficient use of IV fluids, medications, and devices such as needles by facilitating precise control over the amount delivered. This reduces the likelihood of wastage, contributing to cost-effectiveness and resource optimization in healthcare settings;
  • Increased Safety: Valves enhance safety not only for patients but also for healthcare providers by reducing their contact with medical fluids and gases. This feature minimizes the risk of exposure to potentially hazardous substances, promoting a safer working environment for healthcare professionals.

2.Enteral and Parenteral Nutrition Valves

Enteral nutrition, also known as tube feeding, involves delivering nutrition directly to the stomach or small intestine, while parenteral nutrition bypasses the gut entirely.

Valves play a crucial role in both enteral and parenteral feeding systems, offering several advantages:

  • Minimization of Air Intake;
  • Facilitation of Intermittent Feeding;
  • Enhanced Patient Comfort;
  • Reduced Risk of Tube Dislodgment.

3.Medical Diagnostic

For a medical diagnostic procedure such as bronchoscopy, which is used to diagnose or treat conditions affecting the respiratory system, pressurized air or saline solution may be used to inflate the airways for better visualization and to allow the diagnosis of lung disorders. Valves are mandatory for this type of procedure to enable inflation.


Valves are essential in medical drainage systems, preventing backflow, which can lead to infections or complications, by allowing fluids to drain in one direction only. This control is crucial for maintaining the sterility of the system and ensuring that fluids are effectively removed from the body.

Other Non-Surgical Applications

Silicone valves excel in non-surgical medical settings, from drug delivery systems and respiratory devices to home healthcare equipment. Whether in infusion pumps, ventilators, or diagnostic instruments, silicone valves contribute to the seamless operation of non-surgical medical equipment, ultimately improving the quality of care and enhancing the well-being of patients worldwide.

We offer:

  • Development and Design for Manufacturing (DFM) of silicone valves tailored to your non-surgical system, based on your current application, housing, prototype, or initial concept.
