Butterfly Valve (Cast Iron, Lever, 10K)
Model: PMV-26(FC,Lever)
PMV-26(FC,Lever) is a butterfly valve combining a cast iron body with a SUS304 disc, EPDM seat, and a lever-operated manual operator. With a short face-to-face dimension, concentric construction, and 10K pressure rating as standard, it is used for small to medium-bore manual shutoff lines in the water/wastewater, construction, and plant sectors.
Features
- Short face-to-face distance enables installation in confined spaces
- Simple structural design with low defect rate
- Quick open/close for effective fluid control
- High tightness and durability
- Concentric structure with low torque

Frequently Asked Questions
- Why does the lever material differ by size?
- For sizes 40-100A, a cast-iron lever is used for its robustness at lower torque levels. For sizes 125-150A, an aluminum lever is used to reduce weight as the lever becomes longer, easing operator fatigue. The material selection balances operating torque with lever length appropriate to each size range.
- How do I choose between lever and gearbox operation?
- Lever operation completes a 90° stroke in a single handle movement - fast and suitable for emergency shutoff. A gearbox reduces torque for large-bore valves and high differential pressure lines. A gearbox is generally the standard choice for 200A and above or high differential pressure lines.
- How do I choose between cast-iron and stainless steel bodies?
- Cast-iron bodies offer excellent cost competitiveness and are the standard choice for large-bore lines carrying low-corrosivity fluids such as general industrial water, treated water, and HVAC water. For high chloride concentrations, strongly acidic or alkaline fluids, a stainless steel or ductile iron specification should be considered.
- Can the valve be converted to actuated operation?
- By removing the lever operator and attaching a pneumatic or electric actuator to the ISO5211 direct mounting pad, the valve can be converted to automated operation without body replacement. This is well suited for phased automation of manually installed lines.
