2-Way Valves
Elwood’s 2-Way Directional Control Valves provide support in descaling, pump unloading and stop applications.
If Elwood’s standard line of 2-Way Directional Control Valves does not fit your system’s requirements, please request a custom design and our team will design the valve to fit your needs!
Descale Valves
DIN Cartridge Design
This design uses our standard directional control technology. The DIN poppet directional control valves master the poppet design with positive, drop tight sealing. This is achieved by poppet type plunger assemblies with resilient seating discs which close against heated stainless steel mitered seats.
Spindle Style
This style valve uses a balanced spindle design controlled by a pneumatic air cylinder. The opening and closing speeds can be controlled by regulating the airflow entering or exiting the cylinder.
DIN or Spindle Style
- Spindle Sizes 2″ through 12″
- DIN Standard sizes
Capacities to 8,000 GPM (30,000 LPM) - Working pressures to 6,000 psi (414 bar)
- Designed to operate with low viscosity fluids and raw water
- Removable stainless steel internals
- Excellent corrosion resistance
- High reliability
- Long-lasting performance
- Reversible soft composite disc. – DIN
Fluid Flow Technology
- V-notch fluid flow
- Shield seat design
- Inverse fluid flow
Stop Valves
The DIN cartridge style Stop Valve operates using a manual hand wheel in combination with a manually operated pneumatic/hydraulic pilot valve and piston. The pilot valve controls the movement of the piston to open and close the valve. The manual hand wheel is used to provide a positive lock down of the valve.
Features
- Sizes 2″ through 12″
- Capacities to 8,000 GPM (30,000 LPM)
- Working pressures to 6,000 psi (414 bar)
- Designed to operate with low viscosity fluids and raw water
- Removable stainless steel internals
- Excellent corrosion resistance
- High reliability
- Long-lasting performance
- Manual or hydraulically operated pilot
- Reversible soft composite disc
Fluid Flow Technology
- V-notch fluid flow
- Shield seat design
- Inverse fluid flow
Pump Unloading Valves
The Pump Bypass Valve is of a fail open design, utilizing our DIN 2-way valve design. If air or electrical power is lost, the valve will go to the bypass position. In the bypass position, the DIN 2-way valve is in the open position, allowing flow to go over a series of orifices.
Features
- Sizes 2″ through 12″
- Capacities to 8,00 GPM (30,000 LPM)
- Working pressures to 6,000 psi (414 bar)
- Designed to operate with low viscosity fluids and raw water
- Removable stainless steel internals
- Excellent corrosion resistance
- High reliability
- Long-lasting performance
- Manual or hydraulically operated pilot
- Reversible soft composite disc
Fluid Flow Technology
- V-notch fluid flow
- Shield seat design
- Inverse fluid flow
