Specifications
- Models 37 and 38: Control both sides of the irrigation system simultaneously.
- Models 46 and 86: Allow for independent control of each side (twin valves).
- Inlet and Outlet Threads: 80 mm (3"), BSP or NPT Standard.
- Optional Accessories: Solenoids or pilot valves can be added upon request.

Materials
- Models 37, 38, 39: Made from cast iron or cast bronze, with components such as NR rubber diaphragms, SST 302 springs, brass spring discs, and coated steel bolts and nuts.
- Models 46, 86: Made from cast bronze, with similar components but using plastic spring discs and SST 304 bolts and nuts.

- Model 37: L: 305 mm, H: 160 mm
- Model 38: L: 270 mm, H: 160 mm
- Model 39: L: 219 mm, H: 160 mm
- Model 46: L: 350 mm, H: 141 mm
- Model 86: L: 320 mm, H: 141 mm

Operating Pressure Range
- Models 37, 38, 39: 10 - 160 m (14 - 230 psi)
- Models 46, 86: 15 - 160 m (22 - 230 psi) for standard, 7 - 100 m (10 - 140 psi) for low pressure.

Flow Factor (Kv/Cv)
- Models 37/38: Kv: 220, Cv: 257
- Model 39: Kv: 130, Cv: 151
- Models 46/86: Single outlet Kv: 87, Cv: 101; Two outlets Kv: 180, Cv: 210

Ordering Guide
Specify model code when ordering spare parts. Example: Part no. 7 for model 37. Include connection standard (ISO, ANSI) and any additional features like throttling handles.

Additional Information
