What Amresist does
Amresist, Inc. is a Houston, Texas-based manufacturer of high-performance lined industrial valves, organized as a wholly-owned subsidiary of Bray International, Inc. since its 2017 acquisition from KSB Aktiengesellschaft (where it had operated as KSB AMRI, Inc. since founding in 1997). The company designs and produces PFA (Perfluoroalkoxy) lined butterfly valves and ball valves under the Acris® brand, rubber lined butterfly valves under the licensed Isoria© and Mammouth© brands, three PFA lined check valve variants (BCV, SCV, PCV), and complementary C-Series pneumatic rack-and-pinion and MR Series manual quarter-turn actuators. Core engineering differentiators include the proprietary Acriseal™ live-loaded three-step stem sealing system, fully PFA lined disc and body construction with spherically molded interfaces, extended PFA stem protection sleeves, and ISO 15848-1/2 fugitive emissions certification, with operating envelopes spanning -20°F to 400°F, vacuum ratings to 1.03×10⁻² torr, and sizes from ½" up to 160" for the Mammouth large-diameter line.
Amresist sells exclusively through a direct B2B industrial sales motion, accepting customer specifications and quote requests via its website and engaging engineering contractors and process operators for spec-in procurement. Pricing is opaque and quote-based, determined by size, pressure rating, materials, and application specifications, with multi-year contracts typical for major accounts. Target use cases span chemical and petrochemical processing, semiconductor ultra-pure water and chemical delivery, chlor-alkali electrolysis, pharmaceutical and life sciences manufacturing, water and wastewater treatment, mining and mineral processing, pulp and paper, and heavy industrial infrastructure including power, desalination, and steel. Manufacturing is concentrated at the single Houston headquarters and production facility at 2045 Silber Road.
The company competes on domain specialization in PFA lined valves (with claimed leading North American market position), 25+ years of field-proven brand reputation, proprietary stem sealing technology, fugitive emissions compliance, and domestic US manufacturing. It does not disclose revenue, has no independent funding rounds as a subsidiary, operates with 11–50 employees, and currently serves a single-country (USA) market under its own brand while continuing to manufacture and distribute KSB-owned Isoria© and Mammouth© product lines under license.

Amresist product offering
Product offeringCore offering
Amresist manufactures and sells PFA lined and rubber lined industrial valves — including Acris® butterfly valves, Acris® ball valves, Isoria© and Mammouth© rubber lined butterfly valves, and PFA lined check valves — along with pneumatic (C-Series rack and pinion) and manual (MR Series) actuators. Products are custom-specified for corrosive chemical, ultra-pure, chlor-alkali, semiconductor, pharmaceutical, water treatment, and heavy industrial process applications, and sold through direct enterprise field sales on a quote basis.
Product overview
Amresist is a manufacturer of high-performance industrial valves and actuators. The product portfolio centers on two main valve families: PFA (Perfluoroalkoxy) lined valves (Acris® butterfly valves, Acris® ball valves, and three check valve types) designed for corrosive and ultra-pure applications; and rubber lined butterfly valves (Isoria© and Mammouth©) for water management and general industrial use. These are complemented by pneumatic (C-Series rack and pinion) and manual (MR Series) actuators. The company serves chemical, petrochemical, semiconductor, pharmaceutical, water treatment, mining, and pulp and paper industries, with products manufactured in Houston, Texas. The company was formerly KSB AMRI, Inc. and was acquired by Bray International, Inc.

Amresist competitors and assessment
Company assessmentBroad incumbents
- Flowserve Corporation: Flowserve is a major US-listed industrial flow control company offering butterfly, ball, and control valves for chemical, power, oil & gas, and water — the same high-spec corrosive service markets Amresist targets. Highly comparable as a direct substitute supplier for process valve EPC packages.
- ITT Inc. ITT's Industrial Process business produces engineered valves, pumps, and flow control solutions for chemical, mining, and general industrial markets. Comparable as a diversified flow control supplier that competes in chemical and corrosive-service applications.
- KSB Aktiengesellschaft: KSB is Amresist's former parent and current IP licensor for Isoria® and Mammouth® rubber-lined butterfly valves. KSB is a global industrial pump and valve manufacturer headquartered in Germany with overlapping product lines in chemical, water, and power applications, making it a directly comparable flow-control incumbent.
- Crane Co. Crane Co.'s Engineered Materials segment supplies industrial process valves, including lined and severe-service butterfly and ball valves, to chemical, petrochemical, and general industrial customers. Comparable as a multi-line industrial valve manufacturer with overlapping product offering.
- Bray International: Bray International is Amresist's parent company and a global flow control manufacturer with butterfly, ball, and control valves serving similar chemical, water, and HVAC end markets. Comparable as the parent platform that shares overlapping industrial valve portfolios and channels.
- Emerson (Fisher Controls): Emerson's Fisher brand is a leading global supplier of control and severe-service valves for chemical, petrochemical, and power generation process industries — overlapping Amresist's core end markets with comparable butterfly and ball valve offerings at much larger scale.
