Company Profile, Headquartered in Houston Texas USA VOLK Flow Controls Inc is a leading valve manufacturer for the Power . Oil Gas Refining Petrochemical Chemical Mining Metals Pulp Paper and Marine industries with installations. throughout the globe , Valves such as soft seated ball valves gate valves globe valves check valves control valves and instrument. valves together with severe service metal seated zero leakage ball valves and severe service control valves are. available in a wide range of sizes materials and pressure classes . In addition to valves VOLK Flow Controls also offers the GT GIANT TORK complete range of electric and. pneumatic actuators suitable for linear and quarter turn valves . All VOLK Flow Controls products are designed engineered and manufactured by experienced industry engineers. to provide safe reliable dependable and affordable valves actuators and solutions Products are tracked in the. field using our database to monitor performance and service life . VOLK Flow Controls operates a full service valve maintenance facility with a complete scope of work that includes. valve modifications trim end connection cryogenic extension testing and remanufacturing In addition to MRO. maintenance repair and overhaul services and inventory modifications for our customers our maintenance. facility serves as a complete warranty center for all VOLK Flow Controls products . Together with continual feedback from our customers as well as our experience in manufacturing and quality. control VOLK Flow Controls aims to provide our customers the best quality products with the most competitive. pricing on time delivery and full warranty service right here in Houston . VOLK Flow Controls is an ISO 9001 2008 certified corporation with additional certifications that include API 6D . API 602 API 607 and EC Certificate of Conformity VOLK also employs NACE Certified Coating Inspectors full . time to ensure that the finished products are compliant with NACE requirements . ISO 9001 2008 Quality Management System, VOLK Flow Controls is ISO 9001 2008 certified for the design production and sales of valves and valve parts .

VOLK s fully welded ball valve design provides the strength of forged components with durability and uniform. structure that substantially reduces the risk of potential leak paths Engineered for reliable limited upkeep service. in even the most punishing of conditions the VOLK fully welded ball valve is well suited to perform in a wide variety. of pipeline applications , Size 2 to 60 DN 50 to DN 1500 . ANSI Class 150 to 2500,Bolted Body Ball Valve, VOLK s three piece full bore body trunnion mounted ball valves are engineered for a wide scope of diameters . pressure classes and applications Manufactured from carbon steel stainless steel or exotic alloys these forged. valves provide long lasting reliable service for even the most severe of conditions . Size 2 to 60 DN 50 to DN 1500 , ANSI Class 150 to 2500.
Standard Design Features, Positive Blowout Proof Stem. Unlike some designs which use a pin through the stem to achieve blowout. prevention the VOLK design uses oversized split collars around the base of. the stem which creates a diameter larger than the stem and in turn locates. within a recess in the valve body This ensures the stem is held captive at all. times within the valve body unlike pins which have been known to shear and. allow the stem to blow out of the body , Anti static Design. The spring on the stem connects the ball stem and body which can transfer. the static electricity generated during the open close of valves or when the. fluid flows through the cavity avoiding the aggregation of electricity . Emergency Sealant Injection, Emergency sealant injection is designed on seat and stem to ensure sealing under emergency and minimize. Emergency sealant injection on seat Emergency sealant injection on stem. Standard Design Features, Fire Safe Seat, Under fire conditions the metal back up seat ring seals between the seat and the ball as the soft seat melts and. extrudes downstream This provides isolation in accordance with API 607 . Under normal working condition After fire, Double Block Bleed.
VOLK trunnion ball valves are suitable for use in block and bleed applications where fluid in the body is evacuated. through a drain port while both the upstream and downstream pressure are isolated . Optional Features, Single Piston Seat Double Piston Seat. Fluid pressure acts on the surface area of the piston in The force generated by the upstream and downstream. each seat pocket resulting in the seat being pushed fluid pressure pushes the seat on to the ball for the. on to the ball In the event the pressure in the cavity seal Double piston seals cannot self relieve over . is greater than the spring force and fluid pressure pressure in the cavity and a vent valve has to be. the seats are no longer loaded on to the ball Over installed in the cavity for this purpose . pressure in the valve can be relieved in the open or. closed position , SELF RELIEVING SEATS DOUBLE PISTON EFFECT. Extended Stem, Extended stems may be designed and installed onto fully welded ball valves. that will be buried installed underground or in areas that are inaccessible The. extension will be manufactured in accordance with the customer s requirement . Transition Pup, For easier installation onto pipelines transition pups may be welded onto VOLK trunnion ball valve ends . Fully welded Body Ball Valve Exploded View, 20 19 18 17 16 15.
