Nylon and PVC Valves

Nylon and PVC Valve s offer structural simplicity and superior hydraulic performance for surface or subsurface agricultural applications. The valves operate by pipeline or external pressure and the reinforced rubber diaphragm seals the water passage when the line pressure reaches the valve’s control chamber. They are simple to install with slip or threaded connections and available in 1″ to 6″ sizes.

Why Nylon and PVC Valves

  • Superb hydraulic performance.
  • Simple design with only one moving component, the diaphragm, means parts are not located in the water passage way.
  • Low operating pressure.
  • Simple inline installation with minimal maintenance requirements for maximum dependability.

Nylon and PVC Valves Operation

Manual Valve Operation with
a 3-way Selector

  • CLOSED (C): Upstream pressure or pressure from an external source is applied to the control chamber. Initiated by the spring, the diaphragm is pressed down to close the valve drip-tight.
  • OPEN (O): Relieving the water or air pressure to the atmosphere from the control chamber causes the valve to open.
  • AUTOMATIC (A): The automatic port of the 3-Way selector is connected to a solenoid, hydraulic relay or pilot which controls the valve. The common port of the 3-Way selector connects the control chamber to either A, O or C, depending on the direction the selector is pointed.

Product Advantages

  • Durable, corrosion-resistant materials provide high resistance to corrosive water containing fertilizers and chemicals.
  • Nylon valves have threaded connections.
  • PVC valves have threaded or socket (slip) connections allowing pipes to be cemented into the valves.

Applications

  • Ideal for water control in PVC networks
  • Agriculture or Greenhouse and Nursery applications
  • Surface or subsurface installations
  • Portable systems

Specifications
