About Spherical Disc Butterfly Valve

Spherical Disc Valve High-Performance Butterfly Valve

Precise & Strong Durable to 240 C/600 C Temperature and 10 Kg/Cm /20 Kg/Cm Pressure

5 Special Effects:

Compact Design - Full Port - Offers Mass Flow.

Simple Structure, Light & Smooth - Takes a short time for opening & closing with very low torque.

Easy Maintenance - Replaceable seal design.

Self-Sealing: Self-cleaning, the undercut disc segment, and the seal tends to wipe away the material from the sealing area.

Gland pressing plate: Ensure complete utilization of gland seats.Application:

Hygienic Powder & Slurries, especially in pharmaceutical industries.

Versatile Media Compatibility

Engineered to handle a broad spectrum of mediaincluding water, gas, oil, air, and chemicalsthis valves choice of seat and disc materials provides confidence in storage, distribution, and process systems. EPDM, NBR, and PTFE seats ensure optimal sealing across temperature ranges from -20C to +120C.

Flexible Operation and Mounting

Choose your preferred operation method: lever, gearbox, or actuator (manual, pneumatic, or electric), allowing adaptation to on-site needs. The valves innovative design enables mounting in any position, while single-piece or double-flanged bodies and coated exteriors ensure longevity in harsh environments.

Global Standards and Broad Sizing

Complying with ISO 5752 and EN 558 standards and supporting ANSI, DIN, and BS flanges, these valves meet global requirements. Offering sizes from 2 inches up to 48 inches and connections in wafer, lug, and flanged types makes them suitable for a vast array of pipelines.

FAQs of Spherical Disc Butterfly Valve:

Q: How is the Spherical Disc Butterfly Valve operated in industrial settings?

A: This valve can be operated manually using a lever or gearbox, or automatically via pneumatic or electric actuators, enabling tailored control based on the applications automation level and user preference.

Q: What makes the valve suitable for corrosive environments?

A: High corrosion resistance is achieved through the use of epoxy-coated bodies and premium materials like stainless steel and ductile iron for the disc and valve body. This combination ensures reliable performance even with aggressive media.

Q: When should I choose different seat materials like EPDM, NBR, or PTFE?

A: Seat material selection depends on media compatibility and temperature range. EPDM suits water and diluted chemicals, NBR is ideal for oils and gases, while PTFE is preferred for aggressive chemicals and higher temperature resistance.

Q: Where can this butterfly valve be installed within a pipeline?

A: Thanks to its adaptable mounting design, this valve can be installed in any orientationhorizontal, vertical, or inclinedmaking it suitable for varied pipeline layouts and installation requirements.

Q: What are the benefits of using a spherical disc in this butterfly valve?

A: A spherical disc offers enhanced sealing performance, reduced torque for operation, and minimal pressure drop, leading to efficient flow control and lower maintenance over time.

Q: How does compliance with international standards benefit users?

A: Adherence to ISO 5752, EN 558, ANSI, DIN, and BS standards guarantees compatibility with international piping systems and ensures consistent quality, simplifying global sourcing for projects.
