As a shut-off valve for: non-corrosive liquids,
water, saturated steam, oil, air, crude oil and
crude oil products. Operation parameters are
in accordance with ASME/ANSI B 16.34
standard. Application for other working
media or higher temperatures must be
consulted with the manufacturer. Standard
ambient temperature: from -13°F to + 122°F
(-25°C to +50°C). Application for different
working conditions must be discussed with
the manufacturer.

Technical description:
Steel gate valve design complies to API 600
and BS 1414.
Gate valves are yoke, flanged or with butt-
weld ends, with full bore, flexible wedge.
Bodies, bonnets and yokes are cast. Wedges
may be cast or forged. All wedges are guided.
Sealing seats are screwed or welded into
a body. Seats have hard-metal overlay.
The valves have rising, non-rotary stem
bolted body-bonnet joint. Standard stem
threads are Acme 2G-LH.
Gate valves are controlled by handwheel.
After agreement they can be supplied with
bevel gear box or electric servomotor. Larger
sizes 8"of gate valves provided with bearings
for easier operation.
Packing material - die formed rings of
expanded graphite and braided graphite rings.
Gate valve packing meet requirements of
Clean Air Amendment Act of 1990.
Upon special customer´s requirement, gate
valves may be equipped with: drainage,
deaeration, - bypassing from interspace,

Main and connecting dimensions are evident from table Below.

Gate valves are made of the following materials:
ASTM A 216 WCB, A 352 LCC, A 352 LCB, A 217 WC6, A 217 C5,
A 217 C12. Standard gate valve trims are TRIM 1, 5, 8, 10, 11 and 12
according to API 600.

Gate valves are pressure tested according to API 598:
shell test, backseat tightness test, closure tightness by low pressure, closure
tightness by high pressure (if requested in an order).

Yoke gate valves can be installed into pipeline in any position.

Order specification
API 600 Standard applies for ordering. It is necessary to specify in an order:
type number, nominal diameter, pressure class, design (connection),
wedge type, type of control, body and bonnet material, trim material,
operating parameters, acceptance tests, accompanying documentation
