Medical NIST Lockable Line Valve
Medical NIST Lockable Line Valve
A NIST valve provides line isolation with non-interchangeable gas-specific connections, preventing human error in connection and protecting the patient from receiving the wrong gas.
What is it?
Each gas has a unique connection geometry that cannot be fitted to another gas. This type is used where the specification requires demountable connections while guaranteeing no cross-connection; the gas path is verified after installation as part of gas identity and cross-connection testing.
Features
- Gas-specific NIST connections
- Mechanical prevention of cross-connection
- Lockable for operational control
- Suited to demountable connections
- Clear gas and area identification
- Verified during gas identity testing
Applications
- Hospitals and medical complexes
- Operating theatres and intensive care units
- Emergency and inpatient departments
- Dialysis centres
- Day-surgery centres and clinics
- Expansion and refurbishment projects in healthcare facilities

Frequently asked questions
What exactly does a NIST connection add?
It guarantees that a connection for one gas cannot be fitted to another, turning protection from an administrative procedure into a physical mechanical barrier.
