The rotary flanged disc valve, like ball valves, is one of the most modern and progressive types of fittings.
Advantages: small construction dimensions and weight; simplicity of construction, a small number of parts; relative ease of repair, the possibility of quick replacement of sealing elements; the possibility of application for large pipeline diameters.
Recommended by the manufacturer for use
Distinctive features of the gate design are a self-regulating disk inside the seal seat and a single through rod with an external disk position indicator. The gate does not require flange seals during installation.

The rotary disc shutter consists of a cast housing 1, a seat 4 made of synthetic rubber, which is fixed inside the housing, taking its shape. Vulcanized O-rings of circular cross-section are located directly in the saddle (around the stem holes and along the outer profile of the saddle, relief). These features ensure the installation of the gate between the flanges without gaskets, as well as better tightness in relation to the external environment. The locking body is a disc 2, cast, with a square hole for transmitting torque from the rod. The edges of the disc are rounded and polished to facilitate opening and closing. A through rod 3 is installed on top of the housing and the disc. The connection of the disc with the rod is floating, so that the disc self-centers inside the seat. A plate 5 is installed on the flange of the housing, protecting the stem from pulling out and, together with a rubber ring 7, serving for additional sealing of the stem. The plate is fixed with screws 6. The shutter can be equipped with a locking lever for 10 positions, a gearbox with a manual flywheel, a pneumatic actuator of both double action and with a spring return or electric drive.

The FB99 (FB99) series rotary butterfly valve is the most well-known and widespread shut-off valves of this type. This is due to the reliability, durability, low cost and simplicity of the design of products. They are used as shut-off and regulating devices for pipeline transportation of water, gas, petroleum products, alcohols and mildly aggressive media.
A special feature of the design is a self-centering disk mounted on a rotary rod with an external position indicator. The disc shutter is assembled from the following elements:
Metal parts are made of stainless alloy steel grade 12X18NTL. Seals, depending on the characteristics of the working medium, PTFE, EPDM or VITON.
The design of the flanged rotary disc shutter allows the installation of a gearbox, electromechanical or pneumatic drive.
Manufacturer’s warranty is 24 months from the date of sale.
The price of a disc rotary flanged gate varies depending on many factors, including the design of pressure, diameter and material. Additionally, the individual wishes of the customer are taken into account.
You can buy a flanged shutter at a low price in JSC “AK”Phobos” by making an application by phone 8 (800) 700-62-60 (Moscow and all Russia) or using the services of regional managers, as well as by e-mail firstname.lastname@example.org
