Lined Standard ASME Ball Valves BVA

Product catalog summary

Overview: The document provides detailed specifications and features of the Richter Lined Standard ASME Ball Valves, highlighting their design, materials, and applications. These valves are designed for high performance in corrosive and hazardous environments, offering an efficient alternative to plug valves.

Specifications:

Body Lining: 3 mm thick virgin PFA lining with high permeation resistance and vacuum-proof anchoring.
Pressure-Bearing Body: Made of ductile cast iron EN-JS 1049/ASTM A395, designed to absorb system and pipe forces.
Sealing: Permanent body flange sealing with labyrinth-like design for maximum surface pressure and metal centering to withstand pipe forces.
Ball/Stem Design: One-piece design with a stainless steel core, optional Al2O3 ceramic ball for solid-containing fluids.
Seat Rings: Energised PTFE seat rings ensure gas-tight sealing.
Stem Seal: Maintenance-free, gas-tight to EN 12266, with visual inspection capability and manual adjustability.
Mounting Dimensions: Universal ISO 5211.
Corrosion Protection: Body epoxy coated with stainless steel components.

Applications: Suitable for corrosive and hazardous media where stainless steel and other materials are insufficient. They serve as a reliable alternative to lined plug valves due to higher flow rates, lower torques, and minimal maintenance.

Product Features:

PFA-lined one-piece ball/stem unit with optional Al2O3 ceramic ball.
Full ports for sizes 1” and 2” to ASME/ANSI for high flow rates and efficient piping systems.
Reduced port design for sizes 3”, 4”, and 6” for compact design and economic actuation.
Locking devices and gear operators available on request.

Performance:

Operating temperature range from -60 °C (-75 °F) to +200 °C (400 °F) with pressure ratings up to 17.2 bar (250 psi).
Innovative cone shape stem seal design for outstanding performance under challenging conditions.

Dimensions and Weights: Detailed dimensions and weights are provided for various valve sizes, ensuring compatibility with ASME/ANSI standards.

Components and Materials: The document lists the materials used for each component, emphasizing the use of stainless steel and PFA lining for durability and corrosion resistance.

Lined Standard ASME/ANSI Ball Valves Reliable body and seat sealing Fields of application The design of the ball valves series BVA is based on more than 30 years of application experience with lined ball valves. They provide an excellent ratio of economic and operational performance in a wide variety of process applications. The Richter ball valve BVA is designed • as shut-off and automated valves for corrosive and hazardous media, • where stainless steel, special metals, PVDF etc. are not sufficiently corrosion-resistant, • as alternative to valves made of exotic special metals and • serve as...

RICHTER Innovative cone shape stem seal design The PTFE packing insert translates a low axial thrust into a higher radial sealing force by means of the law of cone. The packing gland is designed with a diameter as small as possible. The result: outstanding stem seal performance under the most challenging conditions, permanent preload controlled manual adjustability at any time. An added benefit is the ability to monitor the live loaded condition of the stem seal simply by inspecting the “gap” between the packing followers, thus lending this de- Stem seal design Faxial Spring force Fcone Cone...
