10″ Ductile Iron Wafer Valve with 200 PSI Rating
This 10 inch valve features a ductile iron body designed to withstand demanding industrial service while offering a compact wafer style for easier installation. The 200 PSI rating supports moderate to high-pressure systems, making it a suitable choice for water and air pipelines in commercial or light industrial settings. The 10-position handle enables precise manual control, and the square stem provides a rigid, reliable actuation interface. Keep in mind the alloy choice and seating material when matching to media and temperature requirements.
4″ Ductile Iron Wafer Valve with 200 PSI
Although smaller, this wafer-style valve shares core design features with the 10″ version: a ductile iron body for strength, a 200 PSI rating for reliability under pressure, and a 10-position handle for manual control. The square stem provides consistent torque transfer, ensuring predictable operation in tight spaces or automation-friendly environments. It’s suitable for piping systems where footprint and weight are considerations, such as plant retrofits or smaller-scale distribution lines.
6” Ductile Iron Wafer Valve, 200 PSI
The 6 inch option extends the same durable profile into mid-range pipe sizes. A ductile iron body paired with a 200 PSI rating supports robust service across water and gas distribution networks, depending on media compatibility. The 10-position handle and square stem deliver straightforward manual operation, while the wafer design keeps installation flexible within flanged or butt-wusion connections. Consider the seat material and disc coating to assess corrosion resistance for your media conditions.
UNOX DN250 10″ Wafer Valve with 24V DC Actuator
This wafer-type butterfly valve pairs a GGG40.3 ductile iron body with a 24V DC electric actuator for precise, automated flow control. The EPDM gasket enhances sealing across a wide temperature range, supporting leak-free operation in water and air pipelines. The combination of durable materials and electric actuation makes it suitable for compact automation setups, mobile industrial environments, and retrofit projects where space and reliability are priorities. Check actuator compatibility with your control system voltage and interface requirements.
UNOX DN250 Stainless Disc Butterfly Valve, 10″
The stainless steel disc option adds corrosion resistance for media that may affect iron or for environments with higher humidity or aggressive chemicals. The GGG40.3 body remains highly durable, while EPDM seating maintains reliable sealing under pressure and across temperature ranges. This option is well-suited for water treatment, air handling, and industrial processes where extended service life and reduced maintenance are important. Confirm chemical compatibility and stem design to ensure long-term performance.
Buying Guide: Key Purchase Considerations
- Material and media compatibility: Ductile iron bodies offer strength, but verify disc material and seat compatibility with your media (water, air, other chemicals).
- Pressure rating and size: Ensure the PSI rating matches system pressure; larger valves may require appropriate flanges and supporting hardware.
- Actuation: Manual (handle, stem) versus electric actuators; electric actuation enables automation but requires power and control interfaces (24V DC or other).
- Seal and seating: EPDM is common for water and many HVAC applications; verify temperature range and chemical exposure to prevent leaks.
- Installation style: Wafer valves need compatible mating flanges; consider space, alignment, and support for installation and maintenance access.
- Durability and warranty: Look for corrosion resistance, coating quality, and manufacturer warranty to ensure long-term reliability.
- Maintenance and replacement parts: Access to seals, gaskets, and discs can reduce downtime during service intervals.
Summary: For systems prioritizing durability and straightforward operation, these 10 inch butterfly valves provide robust cores, reliable seals, and flexibility across manual or automated setups. When selecting, match media, temperature, and system pressure with the valve’s materials and actuation options to optimize performance and longevity.
