General Description The model VGU-06 can control and block the abrasive fluid sewage. They are strong equipments to be installed
between flanges, with Wafer Total Lug body, which facilitates the installation and gives a better distribution of the
clamping between the flanges. With Sealing system through Interchangeable Sleeves made of special elastomer,
those which have permanent contact with the knife, this model assures excellent performance, durability and 100%
tightness in both directions, on open / close positions, no accumulation point and contact with the fluid along the
body.

Key Features and Benefits
Can be applied in liquid, humid or dry processes / fluids;
Interchangeable sleeves with permanent contact with the knife, which minimizes the effort / stress of the rubber and assures better resistance and durability for processes with a high number cycles in open and close processes;
Interchangeable seats that offer easy and quick changing, not necessary to dismantle the valve;
Covered passage, avoiding contact of the process / fluid with the body of the valve;
Interchangeable sleeves reforced with steel core;
Full bore and no cavity, which eliminates turbulence, loss of pressure and possible stop of solids on the valve / tubbing;
100% tightness in both directions;
Has knife auto-lubrication system, eliminating the need of frequent maintenance and lubrication of the knife;
Sleeves manufactured with rubber specially developed to assure better durability, resistance and performance to abrasion;
Internal and / or external stem protected by ribbed covering and protection tube, eliminating damage to it in case of aggressive environment;
The retention box has a purging system and amplified cleaning caps to perform preventive maintenance without removing the valve of the process line.
FKB Natural rubber: Very high resistance to abrasion, strain, tear strength and flexibility. Limitations: Low resistance to hydrocarbons, greases, oils, acids and ozone. Maximum temperature 72°C. EPDM: Good abrasion resistance, stress, tear strength and flexibility. Limitations: Low resistance to most fluids based on mineral oil, oil and grease. Maximum temperature 110ºC. Viton: High resistance to work at high temperatures. Excellent resistance to chemical fluids, acids, hydrocarbons,
steam and oils in general. Low tear resistance and oxygenated solvents. Maximum temperature 200°C.
Retention Box
Made of Carbon Steel with drainage system and tamps to make the cleaning easier.
Note:
- It’s very important the period cleaning / drainage of the retention box, in order to not accumulate the fluid, then
causing lock of the open / close operation.
- The passage of the fluid through the retention box occurs only during the valve operation, when the valve is totally
opened or closed, there is no passage.
Superior Sealing (Box Packing)
Made of lubricated gasket in order to ensure no leakage from the Preme and also lubricates the knife to increase
the life of the Passage Seal (Interchangeable sleeves).
Guide of the Knife
Made of metal has the function of guiding the knife so as to eliminate any possibility of misalignment, which would
damage the hoses.
Reinforced Support (Castle)
Built by 4 (four) steel formed sheets and reinforced, which guarantee better support and eliminates the possibility of
warpage of the castle and possible failure of the body in the fixation area.
Stem
Made of stainless steel and designed to support the operation of the valve under maximum pressure, then the level
of slenderness is less than 200.
Hand Starter: Stem is designed to transmit, at least, twice the manual engine output.
Pneumatic, Hydraulic and Electrical Actuators: Stem is designed to transmit, at least, 1.25 times the actuator effort
output.
Protection of the Stem
All valves are equipped with flexible protection on the rod so as to prevent corrosion and / or locking of the valve
due to fouling. When the valve has Manual or Electric Actuator drive, this will also have a protection tube for
External stem (above the steering wheel or electric actuator).
Operation
Manual:
- Manual valves to DN 10" are manufactured with torque relief system and operated directly by the wheel.
- Manual valves to DN 12" and larger are manufactured with reducer gears and operated by steering wheel.
