- Working temperature: -46℃ ~ 121℃ (LU)

- Material class: AA, BB, CC, DD, EE, FF, HH

- Product specification level: PSL1, PSL2, PSL3, PSL3G, PSL4

- Performance requirement: PR1, PR2

- Hard alloy deposited on the seat and gate to improve the anti-abrasion performance of the valveand to increase service life.

- Metal seal between the seat and disc, and between the body and bonnet.

- Outside screwed structure to clearly indicate open/ close positions.

- No contact between the stem thread and medium to reduce stem thread corrosion caused by medium.

- Low torque and reliable seal.

- Working pressure: 2,000 psi ~ 20,000 psi

- Nominal size: 1-13/16" ~ 9" (46mm ~ 230mm)

- Working temperature: -46℃ ~ 121℃ (KU), -18℃ ~ 180℃ (X), -18℃ ~ 345℃ (Y)

- Material class: AA, BB, CC, DD, EE, FF, HH

- Product specification level: PSL1, PSL2, PSL3, PSL3G, PSL4

- Performance requirement: PR1, PR2

- Full bore design, eliminating pressure drop and whirlpool, abating scour of solid particles in liquid.

- Unique seal form (metal seals between body and bonnet, gate and seats) decreases the open/ close torqure dramatically.

- Gate surface is supersonically aprayed with hard alloy coating and the seat rings are made of hard alloy. This provides good wear resistance and corrosion resistance.

- Seat ring is fixed by retainer plate which can maintain good stability.

- Stem has inverted seal structure, making it easy to replace the stem seal packing under pressure.

- One side of the bonnet has a sealant injection valve to supplement sealing grease to improve the sealing and lubrication performance of the seat and gate.

- All specs of EFC gate valves can be fitted with pneumatic (hydraulic) actuators as per user requirement.

- Working pressure: 2,000 psi ~ 10,000 psi

- Nominal size: 1-13/16" ~ 7-1/16" (46mm ~ 180mm)

- Working temperature: -46℃ ~ 121℃ (LU), -18℃ ~ 180℃ (X), -18℃ ~ 345℃ (Y)

- Material class: AA, BB, CC, DD, EE, FF, HH

- Product specification level: PSL1, PSL2, PSL3, PSL3G, PSL4

- Performance requirement: PR1, PR2

- Working medium: oil, gas, mud, gas containing H₂S, CO₂

- Full bore design, eliminating pressure drop and whirlpool, abating scour of solid particles in liquid.

- Gate adopts mechanical seal structure which does not need fluid pressure and has reliable seal.

- Allows low torque operation and low ear in the process of opening/ closing.

- Metal seal between bonnet and body.

- Soft seal or metal seal between gate and seat.

- Periodically injecting grease through the injection valve to enhance the valve sealing performance.

- Working pressure: 2,000 psi ~ 15,000 psi

- Nominal size: 1-13/16" ~ 7-1/16" (46mm ~ 180mm)

- Working temperature: -46℃ ~ 121℃ (LU)

- Material class: AA, BB, CC, DD, EE, FF, HH

- Product specification level: PSL1, PSL2, PSL3, PSL3G, PSL4

- Performance requirement: PR1, PR2

- Working medium: oil, gas, mud, gas containing H₂S, CO₂

- Seat & needle are made of hard alloy to improve corrosion resistance and wear resistance.

- Special packing to stem part, resulting in a reliable seal.

- Light fluid reduces impact and noise.

- Caged type choke valve has low open/ close torque, resulting in advantages of throttle and shut fluid.

- Working pressure: 2,000 psi ~ 5,000 psi

- Nominal
