Medical Gas Ball Valves | Oxygen Cleaned & NFPA 99 Compliant

In medical and laboratory environments, the purity of the gas stream is a matter of life and death. TOT Valve’s Medical Gas Ball Valves are engineered specifically for healthcare facilities, laboratories, and high-purity gas applications.

Our valves are not just “industrial valves”; they undergo a rigorous Oxygen Cleaning Process (meeting CGA G-4.1 and NFPA 99 standards) to ensure they are 100% oil-free, grease-free, and particulate-free, eliminating the risk of combustion in pure oxygen environments.

Key Features & Specifications

1. Oxygen Service Cleaning (The Safety Standard)

Every Medical Gas Shut-off Valve is cleaned in our controlled environment using ultrasonic technology to remove all traces of hydrocarbons. Each valve is then individually capped and sealed in polyethylene bags to maintain purity until installation.

2. Full Port Design for Maximum Flow

Our 2″ Stainless Ball Valves and 1″ Gas Ball Valves feature a full-port design, ensuring minimal pressure drop and maximum flow capacity for critical life-support systems.

3. Material Excellence: 316L Stainless Steel & Carbon Steel

Stainless Steel Ball Valves: Superior corrosion resistance for pharmaceutical and cleanroom applications.
Carbon Steel Ball Valves: High-strength solutions for external Natural Gas Ball Valve lines and non-corrosive gas services.

4. Safety & Compliance

Fire-Safe Design: Tested to API 607 standards for gas-rated service.
Anti-Static Device: Built-in protection to prevent static discharge during high-velocity gas flow.
Blow-out Proof Stem: Ensures operator safety even under unexpected pressure surges.

100% Pressure Testing: Every valve undergoes dual shell and seat testing (hydrostatic and pneumatic) before shipment.
Custom Engineering: Need an extended stem for insulation or a locking handle for security? We offer full customization for Medical Gas Shut-off Valves.

Frequently Asked Questions (FAQ)

Q: Why do medical gas valves need to be “Oil-Free”?

A: In high-concentration oxygen environments, even a trace of hydrocarbon (oil/grease) can act as a fuel, leading to spontaneous combustion or explosions. Our de-greasing process is mandatory for any Oxygen Shut-off Valve.

Q: Are your valves rated for Natural Gas?

A: Yes. Our Natural Gas Ball Valves are designed with reinforced seats and fire-safe seals to handle methane and other combustible gases safely.

Q: Do you provide certification for Oxygen Cleaning?

A: Absolutely. Every shipment of our Med Gas Ball Valves includes a Certificate of Compliance stating the cleaning standard followed (e.g., CGA G-4.1).
