Ball Valve

Industrial Grade Ball Valves for Demanding Applications

ZFV specializes in the design and manufacture of high-integrity ball valves, ranging from 1/2" to 48" and pressure ratings from Class 150 to Class 2500 (PN16–PN420). Engineered for zero-leakage performance, our valves are the trusted choice for critical isolation in global energy and chemical sectors.

Engineered Sealing & Design Features

01.

Anti-Blowout Stem

Designed to prevent stem ejection even under extreme pressure spikes.

02.

Anti-Static Device

Ensures electrical continuity between the ball, stem, and body, preventing spark ignition.

03.

Fire-Safe Design (API 607)

Features secondary metal-to-metal seating to maintain integrity if soft seals are destroyed during a fire.

04.

Double Block and Bleed (DBB)

Available for Trunnion models to allow safe venting of the body cavity while the valve is in the closed position.

Materials and Corrosion Resistance

304 Stainless Steel

Good general corrosion resistance for neutral and mildly corrosive media.

316 Stainless Steel

Improved resistance to chlorides and pitting; recommended for seawater and chloride‑bearing fluids.

Forged Carbon Steel (A105 / LCB)

High strength for elevated temperature and pressure service.

Industry Applications

Oil & Gas

Trunnion ball valves used on pipeline projects to reduce leak incidents and maintenance downtime.

Chemical Processing

Corrosion‑resistant materials extended valve service life and reduced replacement frequency.

Municipal Water

Floating ball valves delivered stable flow control with low maintenance costs.

Custom & OEM Capabilities

Special Designs

Jacketed valves, Extended bonnets for cryogenics, and ESD (Emergency Shutdown) packages.

Actuation-Ready

ISO 5211 mounting pads for easy automation (Pneumatic/Electric).

Bespoke Branding

OEM casting/tagging and custom dimensions (RTJ, BW, Hub ends).

Quality Control

100% Pressure Testing: Every valve undergoes hydrostatic and pneumatic testing per API 598 or API 6D before leaving the factory.
Precision Manufacturing: Our CNC machining centers and spherical grinding machines achieve ball roundness tolerances within microns, significantly extending seat life.

Full Traceability: All shipments include:

MTR (Material Test Reports) per EN 10204 3.1.
Heat number tracking for all pressure-retaining parts.
Detailed pressure test certificates.
Third-Party Inspection: We welcome and facilitate inspections by SGS, TUV, BV, or ABS to verify compliance with your project specifications.

Logistics Support

less Time

4–6 weeks for standard models; stock available for urgent maintenance.

Actuation-Ready

Valves feature ISO 5211 mounting pads for seamless integration with pneumatic, electric, or hydraulic actuators.

Global Shipping

Export-grade reinforced plywood packaging (IPPC certified) ensures your order arrives undamaged at any global port.
