Product Description

This flanged, full port valve offers high performance at an economical price. Available in ANSI 150 and 300, this valve is ideal for automated applications. The 152/302 series is available with a variety of configurations, materials and options.


Two pieces body.


  • Casted full handle (1/2" to 2").

  • Casted handle for lever extension (3" to 8").

  • or Pneumatic or electric actuation.

Design Specifications:

  • ANSI B16.10 - Face to face dimensions.

  • ANSI B16.5 - 150# Flange dimensions.

  • MSS SP72 - Ball valves with flanged or welded ends for general service.

  • NACE-MRO 1-75 - Material Resistance.


The seat design of Rhino Valves allows for flow pressure in either direction to be transferred to the floating ball. This presses the ball against the downstream seat, resulting in bubble-tight sealing. These resilient seats, patented by Rhino, allow for the relief of pressure on the upstream seat against the ball. The result is lower frictional resistance and a long, soft operation, even with high differential pressures. This also lowers the torque required for actuator operation, permitting a smaller, lower cost actuator. The seats also act as a ball scraper, removing any adhered material from the ball for a better sealing.


The stem is designed for both safety and a long, leak-tight service life. Inserted from the bottom through the cavity, it rests securely against an interior body shoulder.

The stem is held in place by a live loaded retaining system, featuring opposing Belleville washers. These flex in response to thermal expansions and contractions and maintain effective sealing pressure as they compensate for normal stem seal wear. The seal can also be easily adjusted in-line by the accessible stem nut. In series 400 and 600, a stem nut retaining clip holds the nut in place and prevents backing off, particularly in high cycle actuated services. In series 152 a CHEVRON® style external stem seal is provided.


The operating torque of the ball valve is influenced by a number of factors whichhave to be considered to properly size a valve actuator. These factors are determined by design (type and material of valve seats), and application (pressure, media and frequency of operation).

The torque shown is in function of the pressure, as the friction between the floating ball and the seat is higher as the pressure is increased.

Note: Our charts were made for reduced port valves (except for Series 152, which can be read directly). If you want to find the torque of a full port valve, please look for the curve of the next higher size, for example if you want to know the torque of a 1" full port valve, you have to see the 1 1/4" valve readout.
