Specification :

manufactures mud valve with reliability, safety, heavy load and corrosion resistance, which is used for a number of oilfield applications, including:
1. drilling standpipe manifold; 2.pump manifold block valves; 3. HP mud mixing lines; 4. HP drilling system block valve; 5. wellheads; 6.well treatment and fracture service; 7.production manifolds; 8. product gathering systems; 9. product flow line.
There are two models of sealing mechanism adopted in sanyi mud valve, that of metal to metal seal, and soft seal.

Metal seal mud valve features
· Long service time for carbide coated disc and seat
· Easy to check the status of valve due to rising stem structure
· Change stem packing without removal of bonnet
· Field maintenance design allows checking the situation of internal parts by opening bonnet and changing valve’ s parts without removing it from pipeline. Soft seal mud valve features
· All parts are interchangeable with DEMCO gate valve manufactured by Cameron.
· In line field repair ability
The bonnet is easily removed for internal parts inspection and/ or replacement without removing the valve from the line; this design simplicity permits fast and easy service without the need for special tools.
· Floating slab gate design
A slab gate with T slot stem connection allows the gate to float to the seat providing a tighter pressure responsive seal.
