Gate valve - SHIGATE | TTV Valves

Elastic Sealing TTV SHIGATE Gate Valve

The TTV SHIGATE is a flanged gate valve with a resilient seated wedge designed for flow isolation in water networks and auxiliary industrial circuits. It operates in an on/off mode and is not intended for throttling or flow regulation, as a partially open position may stress the elastic seating.

Sealing and Testing

The series is rated for full tightness Class VI / ISO 5208 Rate A. Testing and standards include ISO 5208, API 598, EN 12266, and ANSI/ASME B16.34. WRAS approval is noted for potable water installations.

Suitable Media and Applications

Typical Applications:

• Potable and fresh water
• Seawater
• Hot water
• Sewage
• Air and compressed air
• Cooling, irrigation, HVAC
• Metallurgy and auxiliary power station networks

EPDM or NBR selection should be based on the fluid, temperature, and presence of oils, greases, or organic loads.

Certifications and Options

Documentation includes PED 2014/68/EU, ATEX 2014/34/EU, SIL IEC 61508, TA-Luft / ISO 15848 design, and WRAS. Basic operation is manual via handwheel. Automation requires torque control, stem travel, limit switches, and compatibility with electric or pneumatic actuators.

FAQ

Is it suitable for steam?
Not as a standard option. The elastic seating and temperature limit primarily direct it towards water, air, and auxiliary networks.

F4 or F5?
F4 for shorter installation length. F5 when long pattern or replacement of an existing valve with the same face-to-face is required.

EPDM or NBR?
EPDM for water/HVAC. NBR when better performance in sewage or fluids with organic load is needed.
