The Flowseal Soft Seat valve provides a bi-directional bubble tight shutoff (zero leakage) by the use of a patented seat. This unique seat design creates a self-energized seal in vacuum to-low pressure applications.
Under higher pressure conditions, the seat is also designed to permit, confine and direct movement of the soft seat against the disc edge, up to the full ASME Class 150, 300 and 600 Cold Working Pressures.
The Soft Seat is designed for high services with minimal wear and low torque. Seat replacement is a simple operation, requiring no special tools.
Valve Design
- The Flowseal High Performance Butterfly Valve features a double offset (or, double eccentric) shaft design to minimize seat abrasion and lower torque. This double offset design allows the disc to lift off and come away from the seat as it rotates open.
- The Flowseal valve always rotates clockwise to close (when viewed from above) and counterclockwise to open
- The valve body has an overtravel stop which prevents the disc from over rotating into the wrong quadrant. This stop is not to be used as a disc position stop; if the disc contacts the overtravel stop, this means it has rotated beyond the seat.
- The Flowseal valve is bi-directional, but the preferred installation position is with the seat in the upstream position (SUS). Note the arrow on the metal tag attached to the valve body.
Gasket Compatibility
The Flowseal valve is designed to accommodate the use of
standard fiber gaskets (such as non-asbestos, flexible graphite, or equivalent gasket materials) of 1/16" or less, meeting
the dimensional requirements of ASME B16.21–1978.
Thick elastomeric gaskets are not recommended.
Metallic wound (Flexitallic) gaskets may also be used.
Product Identification
- Every Flowseal valve has a metal identification tag attached to the valve body. Information includes the figure
number, the size and pressure class, the materials of
construction, and the operating pressures and temperatures.
- Every Flowseal valve is hydrostatically tested before it is
shipped. The metal tag also includes a serial number; this
number, unique for each valve, is recorded by the Flowseal
Quality Control Department along with the test results and
material certification data, for individual traceability and
verification of every valve produced.
Belimo Actuator SY4-24MFT
Description
The patented gear drive mechanism provides for efficient, smooth operation while allowing easy manual override at any time. Drawing upon years of experience in the actuation industry, we have incorporated the most desirable features into the SY product range.
All units have NEMA 4X ratings, easily visible position indicators, international standard ISO5211 mounting systems, internal thermal motor overload protection, heater, dual auxiliary Form C switches, and easily accessible wiring termination points. Wiring diagrams, included in all printed documentation, are also affixed to the outside of the housing on the permanently attached product label.
The SY actuators are NEMA 4X rated and designed to meet the needs of HVAC and Commercial applications. Offered on Belimo standard and high performance valve series, these actuators are available for on/off and modulating applications.

Once an item is listed, we package and store it in a managed
warehouse. That is why we can offer 1-day shipping. We also select
trucking companies that have reliably picked up our items when scheduled.
There may be a rare exception where the trucking company cannot pickup on the
same or next day. In that case, the handling time is generally out of our
control, but we will communicate the delay to our customers. We always
strive to meet or exceed our shipping and handling obligations.
