    The latest addition to the Triangle Pump Components’ reciprocating pump component family is the WG Sphera series of stem guided, single or dual spring assisted, and caged metal spherical suction and discharge pump valves. With its inception beginning on a wine glass napkin, the WG Sphera series valve has evolved into Triangle Pump Components most flexible valve for a wide variety of different applications ranging from clean to abrasive environments.

    It has been shown that a spherical valve design reduces disruptions to fluid flow as well as fluid turbulence. TPCI’s WG Sphera series valve is a stem-guided design which increases the stability of the valve member while the pump is in operation. Stability of the valve member is further improved by applying the spring pressure over a larger area to reduce variation in the positioning movement of the valve member during operation. The result is a consistent and full opening of the valve with absolute minimal inhibition of fluid direction, fluid velocity, and fluid volume when compared to non-stem guided designs. The result is a reduction in pump vibration and a more consistent rate of flow during operation of your pump. View the technical paper here. The standard WG Sphera series spherical valve is offered in 316 stainless steel or 17-4 hardened stainless steel (other metals upon request), one or two Inconel 600 springs, a 316SS cage, and valve members with or without poly inserts. The use of Inconel 600 springs results in a product that will function properly and longer than an equivalent valve that uses 316 SS springs. The three spring offerings from Triangle Pump Components are:

    • Single light spring for low NPSH conditions
    • Single stronger spring for normal conditions
    • Dual springs for high RPM conditions

    Highly customizable to meet your requirements, each component of the WG Sphera series valve is available individually. These valves are priced similar to the existing AR series valves with the same level of quality that you have come to expect from the Triangle brand.

    Triangle Pump Components Inc. handles high and low volume orders, prototyping, and specialty production. In addition to these capabilities, we offer CAD design and CAM
    programming services to reverse engineer and manufacture parts for customers.

    All of Triangle Pump Components’ valves are proudly manufactured and tested up to the highest industry and specialty standards, including:

    • ASTM
    • ISO 9001:2015 Quality Management System (QMS) Certified
