Gate valves ZSh 65 (50,80,100,150) – 210 (140,160,350,700,1050)
Gate valves ZSH
Purpose:
Wellhead gate valve with metal / metal seal is designed for installation in Christmas tree, used as a shut-off device to completely shut off the flow of the working medium from the well, and valves are also used as part of blowout equipment.
Benefits:
▪ One-piece forged body provides high reliability and minimal dimensions;
▪ The air-tightness of the shutter is ensured by constant compression of the seats;
▪ The gate valves are equipped with an open-close gate position indicator.
▪ the presence of injection and drain valves for carrying out operations on pumping with valves (visual control of the completeness of filling) or draining condensate
▪ execution of shut-off elements made of stainless steels with hardening (chemical heat treatment, surfacing with corrosion-resistant and wear-resistant alloys)
Main technical parameters:
▪ Well environment – oil, gas, gas condensate with solids content up to 25 mg / l, formation water up to 80% by volume;
▪ Climatic modification UHL in accordance with GOST 15150-69;
▪ Placement category I in accordance with GOST 15150–69;
▪ Ambient air temperature from -60 ° С to + 40 ° С;
▪ Working environment temperature up to + 120 ° С;
▪ Shutter tightness class – А according to GOST 9544 – 2005;
▪ Corrosion-resistant design: non-corrosive, corrosive K1 and K2.
▪ It is possible to manufacture with the API 6A monogram according to API standards,
complete set with electric drives, hydraulic drives and control stations.
▪ full or partial cladding of internal surfaces with a corrosion-resistant alloy
▪ level of technical requirements for manufacturing according to GOST / Safety level according to API: UTT1, UTT2, UTT3, UTT4 / PSL1, PSL2, PSL3, PSL3G, PSL4
▪ the level of technical requirements for performance according to GOST / according to API: UTR1, UTR2 / PR1, PR2
▪ API temperature classes: K, L, P, R, S, T, U
▪ Delivery is possible in material versions K1, K2, K3 according to GOST 13846-89 and AA, BB, CC, DD-NL, EE-NL, FF-NL, HH-NL according to API Spec 6A
