Manufacturing & Machining

Silica Sol Investment Casting

Precise wax pattern injection and shell building ensure dense, uniform microstructures and eliminate internal shrinkage voids in pressure zones.

Multi-Axis CNC Machining

High-precision boring of valve body interiors, spherical ball turning, and precise thread/flange facing to maintain tight sealing tolerances.

Automated Assembly & Degreasing

Clean-room or standard assembly lines utilizing specialized torque-controlled tools to ensure consistent operational torque.

Quality Control & Verification

Every production batch undergoes strict quality audits to guarantee zero leakage and long-term cycle durability.

Shell & Seat Hydrostatic Testing: Tested in accordance with API 598 / EN 12266-1 at 1.5x working pressure for shell integrity and 1.1x for seat leakage.

Chemical Composition Analysis: Spectrometric test reports supplied for every heat code to verify alloy grades.

Torque & Cycle Testing: Periodic sample endurance testing verifying smooth operation across thousands of continuous cycles.

Traceability: Permanent heat code laser-etched onto every valve body for complete material tracking.

FAQ

Q: What is the main structural advantage of a 3-piece ball valve over a 2-piece design?

A: A 3-piece ball valve allows the central body housing containing the ball and seats to be swung out or removed entirely from the pipeline by loosening fastening bolts, without disassembling the welded or threaded pipe ends. This significantly reduces maintenance downtime in process plants.

Q: Are your ball valves anti-static and blow-out proof?

A: Yes. All our industrial ball valves feature an internal blow-out proof stem design where the stem is inserted from inside the body cavity. In addition, anti-static devices are incorporated between the ball, stem, and body to safely dissipate potential electrostatic charges.

Q: How do you verify that the stainless steel material meets ASTM CF8M standards?

A: Every melt heat number is analyzed using optical emission spectrometry prior to casting release. We provide EN 10204 3.1 Material Test Certificates (MTC) with every shipment, allowing full verification of chemical and mechanical properties.

Q: What seat material should I choose for high-temperature or chemical applications?

A: Standard pure PTFE is suitable up to approximately 180 degrees Celsius for general chemical use. For higher temperatures, aggressive chemicals, or abrasive media, we recommend reinforced PTFE (RPTFE) or PEEK seats, which offer higher mechanical strength and dimensional stability under load.

Q: Can these ball valves be directly mounted with pneumatic actuators?

A: Yes. All standard industrial ball valves feature an integrated ISO 5211 direct-mounting pad and square stem drive, eliminating the need for extra brackets and couplings when mounting pneumatic or electric actuators.

Q: What pressure testing standards do you follow before factory dispatch?

A: Every individual valve undergoes shell and seat pressure testing in accordance with API 598 and EN 12266-1 standards, ensuring zero leakage across both seating directions prior to packaging and export.
