Diverter Valves | Bucket and Flop Valve Features | Standard Patterns | Options

Options
Heavy Duty Valves
The standard heavy duty valve consists of a 10 gauge abrasion resistant steel liner tack welded to the bottom of the bucket or to the faces of the flop. There are also 10 gauge abrasion resistant steel liners tack welded to the wear sides of the bottom crotch. The housing on the larger size valves is made from one gauge heavier mild steel than what is standard (see the construction standards chart). If the valve has round outlets, then the square to rounds are also made from this heavier gauge.

We offer many other types of construction in place of the above. These include heavier mild steel, many gauges and hardness of abrasion resistant steels, UHMW lining, urethane lining and ceramic tile lining. A customer may also want the valve constructed so that the bucket or flop can be removed for repair without removing the entire valve housing assembly.

Standard Style Electric Operator
Valves can be ordered with an electric drive to provide for remote operation. This is accomplished by a C-face motor, gear reducer, sprockets or shaft coupler and an adjustable slip clutch to protect the mechanical components. A TEFC motor is standard with Class IIG available as an option. Two Class IIG limit switches (SPDT) are standard for use as a motor control and position indicator.

No magnetic starters or controls are supplied. Bucket valves require a reversing set of magnetic starters. Flop valves also require reversing starters as standard but can also be made so that they only require a single starter. The factory should be contacted to make certain in this case as a brake motor is required when a non-reversing started is used.

Electric Linear Actuator
Electrically operated valves can be ordered with a linear actuator drive in place of the standard gear drive described above. There are two limit switches (SPDT) built into the actuator for setting the travel limits. DPDT limit switches are optional. The standard motor is 115 volt single phase. These actuators are available in Class IIG.

Air (or Hydraulic) Operator
All of the different style valves, including 3-way style, are available with an air cylinder operator. The air cylinder is supplied as standard. Solenoid valves are available as options and come in many different styles including valve in head style. Normally double solenoid (double coil) style operators are used so that the bucket or flop will hold its selected position in the event of a power outage. Limit switches are available as options when you want to indicate the position of the bucket or flop.

Valves for Fertilizer Use
All of the different style valves are available for fertilizer service. A standard fertilizer valve consists of a mild steel outer housing with stainless steel interior parts and operating shaft. The housing can be made from all stainless steel as an additional option. The standard stainless steel grade used is 304 with 316 available as an option.

Air operated fertilizer valves come with a 416 stainless steel cylinder rod as standard, unless otherwise specified.

Rack and Pinion Valves
Both 2-way valves and K-style valves are available with internal gates to control material flow direction. These gates can be operated manually or with any other operators already mentioned. Each gates can be operated independently or synchronized so that one closes while the other opens. The factory standard is non-synchronized operation. The standard gates guides are UHMW on the top, bottom and sides of the slide plate. This eliminates metal to metal contact for easy operation and prevents corrosion or buildup of sticky materials. Roller guides are available as an option.

This type of valve is often used in the most heavy duty applications. It provides our most positive protection against leakage and is available with the widest variety of lining options for wear.

Valves with Outlets other than 45° or Horizontal
Whenever a special discharge angle is wanted on a valve our standard construction would be to use a standard 45 degree valve housing with discharges modified as shown in the drawing below. The most commonly requested angles are for use with 60 degree or 52 degree spouting as shown.

We have used this construction method for years without any problems. The diverter face is flatter than the spouting angle but this does not cause a problem since the distance is so short and the product is most always moving at a fairly high velocity.

Custom flop valves can be made where the flop face is at 60 degrees. This requires a taller valve housing. Bucket valves are not available with a steeper face angle.
