Series 2000~5000psi Gate Valve
Expanding Gate Design
Neway's expanding-style gate is a two-piece gate design, connecting with the
stem through the gate major segment, the contact surface between the major
segment and the minor segment is milled V design.
Neway API 6A series GE gate valve is a soft seal or metal-tometal
seal between gate and seats, expanding-style gate
design. Size range is from 2-1/16 to 4-1/16 pressure ratings
from 2.000 PSI to 10.000 PSI, temperature range is from -46
to 121 , material classes range from AA to FF, and available
end connection is double flanged and threaded end.
The V design can force the two segments out and into contact with the seats
when the gate moves up and down, and can produce a positive acting force
against both the upstream and downstream seats or gate guiding plates
simultaneously when the gate is at full close or full open position.
Obviously the expanding-style gate does rely on operation force from handwheel
instead of the line pressure to seal, so it's recommended for applications when a
tight mechanical seal is required.

Note:
1) NRS means non-rising stem gate valve;
2) RS-L means rising stem gate valve with lower balancing stem.
Slab Gate Design
Neway slab-style gate is a simple one-piece & solid gate design, featuring metalto-metal
seal between gate and seats, so as to apply for the most severe and
demanding service condition, including corrosive and abrasive fluid
environments.
A floating-style seat is designed to match with the slab-style gate. In which, a
belleville spring and O-ring between each seat and body ensure a tight seal
against the slab gate.
The slab-style gate design creates a positive seal by moving the floating seat
against the gate with the use of spring energized force, whether low line pressure
or high line pressure.

Neway API 6A series GB gate valve is a simple slab gate, double
stems, and metal-to-metal sealing design providing safe &
dependable service in 10000~15000psi working pressure
application. The import difference from expanding gate valve is to
design a lower balancing stem at the bottom of gate, so as
to reduce the operation torque. Available size range is from
1-13/16 to 4-1/16 , temperature range is from -46 to
121 , material class range from AA to FF.
