Overview

KV Controls’ V-TYPE 1000/2000 are double-offset, high-performance butterfly valves for compact isolation and stable throttling. V-TYPE 1000 serves ASME Class 150 and V-TYPE 2000 serves ASME Class 300. The series follows established high-performance butterfly valve design and test practices and is actuator-ready via ISO 5211 mounting.

Size and end-connection envelope

Nominal sizes: DN50–DN1200 (2″–48″)
Body styles: Wafer, Lug, Double-Flanged

Pressure and temperature capability

Pressure classes: Class 150 (V1000) and Class 300 (V2000)
Typical temperature window (soft-seat builds): approx. –29 °C to ~230 °C, dependent on seat polymer, metallurgy, and medium

Seat, shutoff, and fire-safe options

Soft-seat materials: PTFE, RTFE, and UHMWPE
Shutoff performance: Bi-directional, bubble-tight (zero-leakage) with soft seats
Fire-safe: Options available for hydrocarbon duties according to recognized fire-test standards

Flow characteristic and control behaviour

Inherent characteristic: Modified equal-percentage (typical for double-offset, high-performance butterfly valves)
Installed performance: Predictable gain through mid-stroke and stable throttling in many systems, making the V-TYPE suitable for both isolation and modulating control where a compact package is preferred over a globe valve

Cycle life and durability

Indicative performance: Soft-seat V-TYPE builds have demonstrated zero-leakage after high cycle counts in test conditions around 285 psi.
The double-offset camming action reduces rubbing contact and operating torque, extending seat life. Actual cycle life depends on differential pressure, medium, size, and actuator selection.

Actuation and torque

Mounting: ISO 5211 top mounting for direct pneumatic or electric actuation
Sizing: Use KV Controls torque charts and apply service factors for medium, differential pressure, temperature, and safety. KV Controls sizes actuators and positioners to the worst-case duty.

Compliance and testing (design lineage)

Design & testing practices: align with API 609 and ASME B16.34 for high-performance butterfly valves
Pressure testing: aligns with API 598 / ISO 5208 practices
Fire-safe options: tested to recognized standards such as API 607 and ISO 10497
Quality credentials: typically include ISO 9001 and low-emissions packing qualifications across the portfolio

Materials and trim (typical)

Bodies: Carbon-steel and stainless-steel options
Discs and shafts: Stainless steels with corrosion-resistant overlays or coatings per service
Seats: PTFE, RTFE, UHMWPE soft seats; fire-safe constructions available
Final metallurgy & elastomers: confirmed per medium, temperature, and applicable standards

Installation and integration notes

Face-to-face and piping dimensions follow common high-performance butterfly valve practices; select wafer, lug, or flanged to suit isolation strategy and maintenance philosophy.
Combine with pneumatic or electric actuators and smart positioners for closed-loop control, sized from torque data for your duty case.
