They regulate the intake and output of drilling fluid. The suction valve allows mud to enter the pump chamber during the intake stroke, while the discharge valve allows pressurized fluid to exit during the discharge stroke, preventing backflow and maintaining pressure.
Materials on file include high-chrome alloy steel, tungsten carbide, polyurethane, and stainless steel. The body material is typically carbon steel (ASTM A216 WCB), and the seat material is PTFE. Material selection depends on the abrasive nature of the drilling fluid and operating conditions.
The operating pressure range is 1.0–1.6 MPa, and the operating temperature range is -20 to 80 °C. These are reference values; actual limits depend on the specific valve model and application.
Check the leakage rate (≤0.01 mL/min per ISO 5208 Class VI), seat hardness (55–62 HRC per ASTM E18), and test pressure (1.5–2.4 MPa). Always confirm these values with the manufacturer for the specific model.
