In 1983 Novatech pioneered the manufacture of the original inertia welded unibody valve design. This valve, manufactured by Novatech and marketed under other brand labels, became the standard of the industry. The Novatech valve combines the advantages of a forging with the advantages of an investment casting; the forged alloy steel upper body assures impact strength and the precision cast guide legs minimize flow restrictions and fluid turbulence.
All Novatech valves and seats are manufactured to rigid quality control standards that include: CNC machining for exact dimensional tolerance control, heat treat carburizing with a deep hard wear case, full metallurgical laboratory tests on every furnace load, and seat tapers that are 100% gage inspected to meet pump manufacturer's exact dimensional specifications. Valve inserts feature a high strength, abrasion-resistant polyurethane; all inserts are machined after molding to exact thickness tolerances.
Novatech manufactures a wide variety of valves, seats, caged assemblies for almost all well service pumps and applications; including work-over, cementing, acidizing, and fracturing.

Novatech is the leader in full open valve and seat technology; the first valves and seats in the industry rated for continuous service at 7500 psi. The Novatech design incorporates many of the features proven in the Novatech Well Service Valves & Seats, plus the following improvements:
1. Massive, rigid full open seat design, results in reduced fluid end cracking and washouts! Uniform seat loads against the fluid end deck eliminates washouts commonly caused by non-uniform seat loads form web seats.
2. Extra large seat bearing area spreads valve load over larger area, reduces metal wear, and increases valve and seat life.
3.CAST-N-PLACE (Patent Pending) insert design locks insert in groove, eliminates underside insert washes, the most frequent cause of premature insert failures. CAST-N-PLACE technique reduces stress on the valve insert during molding, to increase insert life. Ideal for LCM muds.
Heavy-duty puller head, pulls seats in the most difficult conditions.
