Ball Valves for Industrial Applications

Operating Principle and Body Designs

A ball valve shuts off the medium by rotating a bored ball 90° between two seat rings. In the open position, the bore aligns with the pipe bore — with full bore, the free cross-section matches the pipe inside diameter. This produces the characteristic advantages: minimal pressure drop, piggable pipe runs, fast switching and unambiguous position indication from the lever.

FERGO supplies ball valves in two-piece and three-piece body designs. The three-piece construction allows seat ring maintenance while the valve stays in line, without dismantling the pipework — a decisive advantage with abrasive or polymerising media. The KH104, KH105, KH109 and KH113 series cover threaded connections to ISO 228-1, ISO 7-1 and ASME B1.20.1. Flanged connections are covered by KH155, KH120, KH121 and the compact KH156, and weldable lines by the KH154 with weld ends to ANSI B16.25.

Beyond pure isolation, the three-way KL103, KL112, KL113 and KT112 series handle diverting and mixing duties. The L-port switches between two lines, while the T-port connects or distributes three ports. Every series carries an ISO 5211 mounting flange and can be automated without adapters.

PRODUCT GROUPS

01 Ball Valves by Connection and Configuration

Threaded Ball Valves

Threaded ball valves of the KH104, KH105, KH109 and KH113 series in stainless steel 1.4408 and brass CW617N, DN8–DN100. Female threads to ISO 228-1, ISO 7-1 or ASME B1.20.1 (NPT). Two-piece and three-piece bodies, full bore.

Flanged Ball Valves

Flanged ball valves KH155, KH120, KH121 and the compact KH156, DN15–DN300, PN10–PN40 and ANSI 150. Bodies in stainless steel 1.4408, cast steel 1.0619 or GGG40. Face-to-face dimensions to EN 558 series F4 and F1 plus a shortened compact version.

Weld End Ball Valves

Weld end ball valves of the KH154 series with butt-weld or socket-weld ends to ANSI B16.25. The welded joint eliminates flange gaskets as a leak path — standard practice in steam, thermal oil and high-pressure lines up to PN100.

Three-Way Ball Valves

Three-way ball valves KL103, KL112, KL113 and KT112 with L-port for diverting or T-port for mixing and distributing. Threaded and flanged versions, stainless steel and brass, reduced bore.

Pneumatic Ball Valves

Pneumatic ball valves with double-acting (DA) or spring-return single-acting (SR) quarter-turn actuators. Fail-safe position NO or NC freely selectable, ATEX compliant, with NAMUR interface for solenoid valve and position feedback.

Electric Ball Valves

Electric ball valves with J4C rotary actuator, multi-voltage 24–240 V AC/DC, IP67 protection. Optionally with positioner for modulating control or battery spring return (BSR) as a fail-safe position on power loss.

DVGW Ball Valves for Drinking Water and Gas

DVGW-certified ball valves to DIN EN 13774. KH123W and KH124W series for drinking water, KH122G and KH124G for gas. Brass CW617N, stainless steel and GGG40.

Special Material Ball Valves

Special material ball valves for the chemical industry — duplex and other corrosion-resistant alloys for chloride-bearing, acidic and heavily loaded process media.

TECHNICAL DESCRIPTION

Materials, Seats and Actuation

Body Materials

Stainless steel 1.4408 (CF8M / AISI 316) is the standard material for process applications and offers increased resistance to chlorides and acids through its molybdenum content. Cast steel 1.0619 (ASTM A216 WCB) is used for steam, thermal oil and higher pressures where mechanical strength is the priority. Ductile iron GGG40 covers water, wastewater and utility applications economically. Brass CW617N is the proven solution for domestic installation, compressed air and heating systems from DN8 to DN50.

Seat Materials and Sealing System

The seat ring determines the temperature range and chemical resistance of a ball valve. TFM 1600 — a modified PTFE — operates from –29 °C to +175 °C and shows markedly less cold flow than standard PTFE, which keeps sealing performance stable over long service intervals. PTFE with 15 % glass fibre improves pressure and dimensional stability at higher temperatures. Virgin PTFE offers the broadest chemical resistance at moderate pressures. FKM/Viton completes the range for mineral oils, fuels and petrochemical media. The stem is double-sealed to atmosphere and, in the TA-Luft version, additionally secured against fugitive emissions.

Bore, Two-Way and Three-Way

With full bore, the ball bore matches the pipe inside diameter — pressure drop stays minimal, and the line remains piggable. Reduced bore drops the ball by one nominal size and lowers weight, operating torque and purchase cost, but introduces a measurable pressure drop. In three-way form, the L-port switches flow between two outlets, while the T-port mixes two inlets or splits one inlet across two lines.

Actuation and Automation

The ISO 5211 mounting flange allows adapter-free fitting of hand levers, worm gearboxes, pneumatic quarter-turn actuators or electric actuators. For process automation, NAMUR solenoid valves, limit switch boxes for position feedback and positioners for modulating control complete the valve into a full automation assembly.

APPLICATIONS

Applications and Industries

Chemical and Petrochemical Processing

Aggressive and solvent-bearing media call for stainless steel 1.4408 with TFM 1600 or PTFE seats. Volatile hydrocarbons require the TA-Luft version with reinforced stem sealing, and hazardous areas additionally require ATEX conformity to 2014/34/EU. Where fire is a risk, Fire Safe versions to API 607 or ISO 10497 seal metal-to-metal once the PTFE seat has burned away. NACE MR 0175 is available for sour service. FERGO also supplies special material ball valves such as duplex for chloride-bearing processes.

Drinking Water Supply and Water Treatment

Drinking water networks, service connections and treatment plants use DVGW-certified ball valves. Brass CW617N covers domestic installation, while stainless steel and GGG40 serve network and plant engineering. The KH123W and KH124W series are designed specifically for potable water.

Gas Supply and Distribution

For natural gas and LPG, the KH122G and KH124G series carry DVGW approval to DIN EN 13774. What matters here is the combination of gas-rated stem sealing, verified tightness under cycling and unambiguous position indication for isolation valves in distribution infrastructure.

Steam, Thermal Oil and Power Generation

Saturated steam and thermal oil circuits need temperature-stable seats. PTFE with 15 % glass fibre significantly improves dimensional stability under pressure and temperature compared with virgin PTFE. For safety-instrumented shutdown in boiler plants and process furnaces, FERGO offers ball valves with SIL 3 suitability and spring-return actuators that move to the safe position automatically on loss of power.

HVAC, Building Services and Compressed Air

In heating, cooling and compressed air networks, brass and stainless steel ball valves handle riser and equipment isolation. The low pressure drop of a full bore design translates directly into pump and compressor energy savings. Three-way ball valves with L-port replace two separate valves in manifolds and save installation space.

Food, Beverage and Pharmaceutical Production

Stainless steel 1.4408 with PTFE or TFM 1600 seats meets cleanability and media compatibility requirements. The three-piece design simplifies inspection in CIP circuits, and full bore prevents deposits and dead legs in product lines.

STANDARDS AND CERTIFICATIONS

FERGO ball valves comply with the Pressure Equipment Directive 2014/68/EU across the entire range. Threaded connections conform to ISO 228-1, ISO 7-1 and ASME B1.20.1, flanged connections to EN 1092-1 and ASME B16.5 Class 150 and 300, and weld ends to ANSI B16.25. DVGW approval to DIN EN 13774 applies to drinking water and gas versions. TA-Luft conformity is available for emission-critical applications and ATEX conformity to 2014/34/EU for potentially explosive atmospheres. Fire Safe versions are tested to API 607 or ISO 10497, and safety-instrumented applications are covered up to SIL 3. AD2000-A4 and NACE MR 0175 are available in addition.
