Industrial Valves

When turned open, the disc of the gate is completely removed allowing materials to pass. even though this gives the valve good shut-off property and bidirectional, they cannot be quickly open or close and are responsive to shaking when open.

Gate Valves Features

• Swastik Industries Steel Gate Valves have been designed to meet the requirements of API 600 / BS 1414 / API 603 / API 6D /ASME B 16.34
• Face to Face and End to End dimensions conform to ASME B 16.10 /BS 2080 / DIN
• End flange dimensions conform to ASME B 16.5 / API 605 / BS 3293 / DIN
• Butt weld end dimensions conform to ASME B 16.25
• The stem nut design allows for the removal of the hand-wheel while keeping the Stem and Gate in a fixed position.
• Anti-frictional Ball bearings are provided in higher sizes and classes.
• The strength of Stem to Gate connection is stronger than the strength of the Stem at the root of the operating thread
• Outside screw and yoke construction
• Bi-directional shut-off
• The gland is of self aligning two piece type Deep stuffing box
• Body ports are streamlined, permitting unobstructed flow, reduces turbulence, results in lower pressure drop & lower erosion
• The Seat-rings are cylindrical bottom seated type having ample cross section for strength are provided with welded in and threaded Seat-rings will be supplied on request. In case of SS valves the Seat-rings are integral to Body
• The Body to Bonnet joint is flat in ASME 150# valves, a male and female joint is used in 300# & 600# and ring joint is used in higher classes
• Gate Valves meet the requirements of fugitive emission levels Shell category B as per MESC SPE 77/312

Gate Valves Options

• Solid, flexible, split wedge, double disc and parallel Slide Gate configurations available
• For low temperature and cryogenic services (cold box and non-cold box applications) extended bonnet as per BS 6364 available
• Locking arrangement
• Gear, Electrical, Hydraulic or Pneumatic actuator available

Gate Valves Options

We Smitvalves is providing Gate Valves which are beneficial for applications involving slurries, as their “gates” can cut right through the slurry. Gate Valvesare also used in applications that involve viscous liquids such as heavy oils, light grease, varnish, molasses etc. Gate Valves are available in large sizes for handling thick flow. However, gate valves deny low pressure and are not optimal in applications that require sanitary conditions. Gate valves are excellent to use where a shutoff valve is needed. If required, gate valves can also be used for choking applications. However, this is not generally recommended as erosion occurs due to the vibrations of the disk in throttling applications.

Gate Valves manufacturers are designed to minimize pressure drop across the gate valve in the fully opened position and stop the flow of fluid completely. The direction of the fluid remains the same and the diameter through which the process fluid passes is essentially equal to the pipe. Hence, they have minimal pressure drop when opened fully.Gate valves are generally fully opened or fully closed. The disk of a Gate Valves is completely removed when the valve is fully open and the disk is fully drawn up into the gate valve Bonnet. A Gate valve can be used for a wide range of liquids and provides a tight seal when closed.
