The Y-type forged steel gate valve is a valve with various design forms and wide application scenarios.

Design Style

The Y-type forged steel check valves come in three main types of bonnet designs:

Bolted Flange Cover: The valve body and cover are connected by bolts and nuts, sealed with a spiral wound gasket (made of 316 stainless steel and flexible graphite). Metal ring connections are also available upon customer's special request.

Welded Valve Cover: The valve body and cover are connected by a threaded joint, utilizing full-welded sealing. A full-welded two-joint connection can also be used upon special customer requirements.

Pressure Self-tightening Valve Cover: The valve body and cover are connected by a threaded connection, sealed with an internal pressure self-sealing ring.

Application Scenarios and Performance Features

The Y-type forged steel stop valve is suitable for various operating conditions and media, featuring the following characteristics:

‌High Pressure Resistance: Pressure rating up to PN100, operating temperature of 425°C._

Low Flow Resistance Design: The Y-type patented structure reduces fluid resistance by 60% and increases flow rate by 40%.

‌Long-life Sealing: Hard alloy surfacing on sealing surface ensures zero leakage for 100,000 cycles, passed API 598 sealing test.‌

‌Wear Resistance: Special surface hardening treatment increases wear resistance by 5 times, suitable for abrasive media conditions._

‌Intelligent Operation Experience: Low-torque design increases operational efficiency by 40%, and the blowout-proof valve rod structure passes the API 607 fire resistance test._

Material and Standards

Material and standards for the Y-type forged steel stop valve:

Material: The valve body is forged from ASTM A105, the sealing surface is hard alloy surfacing, and the valve stem and seat are made of stainless steel material.

Standard: Compliant with ANSI B16.34, API 598, and MSS-SP-25 standards.
