(gear operated butterfly valve price)
Gear-operated butterfly valves are critical for industrial flow control, with prices typically ranging from $150 to $3,500 depending on specifications. The worm gear variant accounts for 62% of global sales due to its balance between cost and torque efficiency. Market data shows a 7.3% annual price fluctuation for stainless steel models, driven by raw material costs. Unlike manual valves, gear-operated designs reduce labor expenses by 18-22% in high-cycle operations.
Gear mechanisms enhance valve performance through: • 340% increased torque accuracy compared to lever handles • Extended service life (8-12 years vs. 5-7 years for manual valves) • 150% faster shutoff in emergency scenarios Premium models like the wafer-type GD-47X series withstand 250 PSI at 400°F, making them ideal for steam applications. The gearbox's IP67 rating ensures reliability in harsh environments.
Brand | Model | Price Range | Pressure Rating | Lead Time |
---|---|---|---|---|
ValvTechnik | VG-912W | $880-$1,450 | ANSI 150 | 4 weeks |
DeZURIK | GBC-32 | $1,200-$2,100 | ANSI 300 | 6 weeks |
Bray | 31NGF | $650-$980 | PN16 | 2 weeks |
Customization impacts pricing by 15-40% through: 1. Material upgrades (e.g., Hastelloy seats add $420-$600) 2. Gear ratios optimized for high-viscosity fluids 3. ATEX-certified actuators for explosive environments A recent chemical plant project saved $78,000 annually by specifying 316L stainless steel valves with 20:1 gear reducers.
• Oil & Gas: 24" worm gear valves reduced pipeline maintenance costs by 34% in Permian Basin operations • HVAC: Wafer-type valves cut installation time by 42% in commercial buildings • Water Treatment: Custom gearboxes increased valve cycle life by 3.8x in desalination plants
Component | Price Influence |- Body Material | 55-60% Gear Type | 20-25% Size (2"-48") | 15-18% Certification | 5-12% Carbon steel 8" valves average $385 vs. $1,240 for duplex stainless steel equivalents. API 609 compliance adds 18-22% to baseline costs.
While initial costs exceed manual valves by 120-150%, lifecycle analysis shows: • 31% lower TCO over 10 years • 92% reduced downtime risk • ROI within 18-24 months for continuous processes The wafer-type VG-200 series demonstrates this value proposition, achieving 1.2 million cycles without maintenance in power generation tests.
(gear operated butterfly valve price)
A: The price depends on valve size, material (e.g., cast iron, stainless steel), pressure rating, and brand reputation. Additional costs may include certifications or customizations.
A: Wafer-type valves are typically cheaper than lug-type due to simpler design and fewer components. However, pricing varies based on material and application requirements.
A: Yes, worm gear valves often cost more due to their precision control and durable gear mechanism. Lever-operated valves are cheaper but offer less torque accuracy.
A: Compare prices from manufacturers, authorized distributors, or industrial suppliers online. Bulk purchases or long-term contracts may offer discounts.
A: Not always, but reputable brands with certifications (e.g., ISO, API) often justify higher prices. Evaluate specifications and reviews alongside cost.
