The TSC DM style Gate Valve, with superior design features precision workmanship and a proven principle are engineered to meet the harsh drilling requirements in today oilfield.

The TSC Valve conforms to the standard flange dimensions and pressure rating of 3000 and 5000 PSI working pressure and temperature service up to 400°F.

The TSC Valve standard trim includes 316SS Gates and Buna N seats, optional trims are available which include Ni Plated Carbon Steel, Monel and Aluminum Bronze gates. Seats are offered in Viton and Hypalon optional 303SS Stem is available.

Construction

All the TSC Valve conforms to API flange dimensions in all pressure class ratings. The valves have rising stems that are driven by a double threaded hub for quick opening and closing with minimum turning effort. The permanently lubricated stems and stem screws are fully sealed assembly consisting of homogenous and fabric backed rings for high and low pressure sealings.

Applications

• Drilling and well-treating chemicals
• Sour gas and crude oil
• Abrasive drilling mud
• Pipelines and manifolds
• Wellheads
• Water, oil and gas lines
• Cements and slurries
• Corrosive water flood lines
• Fahrenheit services

Seat Elastomers

Buna N (nitrile) is the basic seat elastomer. It is excellent for petroleum oil and gases, fuel oils and alcohols from-10° F to +200°F. Hypalon is optionally offered compounded for maximum chemical resistance. Particularly suited for oxidizing acids and hydrocarbons and resists moderate concentrations of hydrogen sulphide. Serviceable from-10°F to+400°F.

PLASTIC COATINGS

Internally plastic-coated valve bodies and bonnet are available on request.

TESTING

TSC Gate Valves are hydrostatically tested at assembly. Stem seal, body and seat are inspected for zero leakage under pressure, before acceptance.

PRESSURE RATINGS

MKP Gate Valves are designed for the maximum working pressure and test pressure tabulated below:

ORDERING INFORMATION

Provide size, pressure and end connection. Specify pressure class of flanged ends and raised face or RTJ. For threaded ends, give line pipe, NUE (non upset tubing) or EUE (external upset tubing). For weld or grooved ends, provide schedule of mating pipe.
