Gosco Valves from John Brooks Company

Gosco High Performance Valves

Gosco Valves are manufactured for Severe Service – Metal or Soft Seated Ball Valves

Gosco Valves include high performance metal seated “M-Class” (Made-to-Order) ball valves and a wide variety of soft seated isolation & control valves, as well as a full cryogenic line. Gosco Valves have solved problems in the toughest applications for over 30 years. 

• Abrasive –  materials, coatings and hardening processes, as well as designs to reduce velocities and cavitation
• High Temperature – metal seats, and Class VI shut-off to 1200 ºF/649 ºC
• Corrosive –materials such as Hastelloy, Inconel, Titanium, Alloy 20 and more
• High Cycle – 1,000,000 cycle packing guarantee i
• Cryogenic –we offer the Dual Pak with a full cryogenic extension to cover -270 ºC/-436 ºF

	F-Class Metal Seated Ball Valves – Fast, Flexible Flawless Metal-Seated Ball Valves Features & Benefits: Lockable T-handle, gearbox and actuated options Oversized shaft to prevent twisting Horseshoe body plates are made from less expensive WC6 (F11) material. Since they are not wetted components, they do not have to be the same material as the body, bonnet and flanges Optional dual packing sets eliminate shaft leaks Blow-out proof shaft design ensures safety Pressures up to Class 600 ANSI/DIN/RTJ flanged, butt weld, NPT, BSPT, and socket weld end connections Ball and seats have the most advanced coating/surface hardening technology options available, to provide the best solution for critical applications Metal ball and seats are lap matched to provide tight shut-off Only four components (body, bonnet and flanges) need to be manufactured on demand for any valve, regardless of size, pressure class or material. Available in all commercially available materials (Hastelloy, Alloy 20, Duplex, etc.) Fully bi-directional live loaded seats compensate for thermal and pressure variances, ensuring the best possible seal, even at low pressures Arcuate cut ball for abrasive or high velocity applications. Optional Vari-V ball for precise flow control applications Patented scalloped ring to prevent build-up of material between the seat and the spring F-Class Valves Include: Gosco F-Class Soft or Metal Seated Valves Gosco F-Class Block & Bleed Valves Gosco F-Class Vari-V Control Valves
	M-Class Metal Seated Ball Valves – Advanced Coating/Service Harding technology on Ball & Seats for Critical Applications Features & Benefits: Lockable tee-handle option Patented tripod mounting bracket with ISO 5211 option for simple and precise actuator mounting Oversized stem to prevent twisting Dual live loaded packing sets eliminate stem leaks Blow-out proof stem design ensures safety Live loaded body and bonnet bolts compensate for thermal expansion, pressure fluctuations and vibration Live loaded seats compensate for thermal and pressure variances, ensuring the best possible seal, even at low pressures Pressures up to 4500# class Flanged, socket weld, butt weld, threaded and non-standard end connections Ball and seats have the most advanced coating/surface hardening technology options available, to provide the best solution for critical applications Arcuate cut ball for abrasive or high velocity applications Patented scalloped seat to prevent build-up of material between the seat and the spring Metal ball and seats are lap matched to provide bubble-tight shut-off Available in all commercially available materials (Hastelloy, Alloy 20, Titanium, Duplex, Monel, Zirconium, etc.) M-Class Valves Include: Gosco M-Class Metal Seated Ball Valves Gosco M-Class 3-Way Diverter Valves Gosco M-Class Block & Bleed Valves Gosco M-Class Cryogenic Valves Gosco M-Class Vari-V Metal Seated Control Valves
	Gosco S-Class Soft Seated Ball Valves – Add Optional Components, Treatments/Coatings, and Accessories for Your Application Features & Benefits: Lockable Tee Handle Option Clearview Mounting Pad Upper Stem Guide Independently Live Loaded Upper Packing Extended Bonnet for Insulation Optional Fugitive Emission Port Lower Stem Guide Independently Live Loaded Lower Packing Fully Encapsulated End Cap Seals Wide Variety of Seal Options Fully Grounded Stem, Ball & Body Complete Range of Body & Trim Materials (Including High Alloys) Multiple End Connections (Including Flanged – Welded – Threaded – Sanitary or Customer Specified S-Class Valves Include: Gosco S-Class Soft Seated Ball Valves Gosco S-Class 3-Way Diverter Valves Gosco S-Class Block & Bleed Valves Gosco S-Class Cryogenic Valves Gosco S-Class Vari-V Control Valves
