Hydraulic Fracturing Gate Valve

Fracturing gate valve is applied in fracturing project and it is 

an important part for fracturing equipment. The fracturing 

gate valve is designed in accordance with performance 

requirements of API 6A. The fracturing gate valve manufactured 

by Douson has maximum drift of 7-1/16" and maximum 

pressure of 20000psi, which has acquired patent for national 

invention and patent for utility model. Fracturing technology 

adopted by Douson is internationally advanced technology.

Product Performance Features:

It is designed and manufactured in accordance API 6A with 

material shall meet the requirements of NACE MR0175;

Full bore forged steel type gate valve can be characterized 

as high pressure resistance, erosion resistance;.

Body-bonnet and wedge-seat are full metal sealing structure,

which is reliable;Seat-seat rings, body-seat rings using 

high-performance seal ring assisted sealing;

Seat-body shall be sealed in assistance of two elastic

accumulative rings, in this way, low pressure seal can be 

obtained and surface contamination can be avoid;Floating seat 

structure, bi-directional sealing;Valve cap, tail cap and valve 

stem shall be designed as back seal, which is convenient to 

replace packing with pressure;A sealing grease injection valve, 

easy online maintenance online, improve life.

Triple slice structure, easy maintenance and cleaning. Piston 

type hydraulic actuator can realize remote control and fast 

switch valve. It can realize interchange in the similar valve in 

overseas well product. With manual locking device. It can be 

manually locked in the normally closed
