NH₃ (Anhydrous Ammonia) Bleeder Valves

NH₃ anhydrous ammonia bleeder valves are critical safety components designed to safely release trapped anhydrous ammonia gas or liquid from hoses, couplings, and valves during service or disconnection. Built for reliability and compliance, these ammonia valves ensure controlled venting and operator protection in agricultural and industrial NH₃ systems.

Available in multiple sizes and configurations, our bleeder valves feature durable construction, precise operation, and corrosion-resistant materials ideal for the demanding conditions of ammonia application systems.

Reliable Bleeder Valves for Safe NH₃ Handling

Our range of anhydrous ammonia bleeder valves are manufactured by Continental, a trusted name in ammonia equipment. 

Built for precision and safety, our NH₃ anhydrous ammonia bleeder valves feature:

  • Controlled venting – safely releases trapped liquid or vapour NH₃ before hose or fitting disconnection.
  • High-quality construction – brass or stainless-steel bodies resist corrosion and wear in agricultural environments.
  • Chemical-resistant seals – Teflon or Viton materials ensure a leak-free seal even under high pressure.
  • User-friendly operation – Available in both T-handle and knurled handle designs for operator preference.
  • Extended tube option – A-410 model includes a 12" vent tube to direct gas away from the operator for added safety.

Frequently Asked Question

A bleeder valve is a controlled pressure release point. It allows operators to safely vent trapped gas or liquid from a closed system before disconnecting fittings, performing maintenance, or verifying system pressure. In anhydrous ammonia (NH₃) applications, this ensures that residual pressure is released in a controlled way to prevent a sudden discharge or harmful chemicals.

On NH₃ tanks, bleeder valves are used to safely vent ammonia vapor or liquid when filling, emptying, or servicing the tank. They help confirm liquid levels and relieve excess pressure during transfer operations. Each bleeder valve provides a controlled outlet so that any trapped NH₃ can be released safely, protecting both the operator and equipment.

Anhydrous ammonia is stored under pressure and can cause severe burns, frostbite, or respiratory harm if released suddenly. Bleeder valves are critical safety components because they allow the operator to release pressure gradually, preventing uncontrolled ammonia discharge. By venting small amounts of trapped gas before disconnecting hoses or fittings, bleeder valves help ensure a safer, more controlled working environment.

A malfunctioning or damaged bleeder valve can lead to serious safety hazards, including: Uncontrolled ammonia release due to stuck or leaking valve components. Pressure buildup that prevents safe disconnection of hoses or fittings. Chemical burns or frostbite from escaping liquid or vapor. Environmental and equipment damage from ammonia exposure or corrosion. Routine inspection and maintenance of bleeder valves are essential to ensure safe operation and compliance with NH₃ handling standards.
