From a 1967 trading house to a valve supply expert
Every distributor promises to be around next year. This one can point at 1967. Optimus Distributor is owned and managed by the grandchildren of the late Dato' Loh Eng Shuan, whose trading company — Loh Eng Shuan Company Sdn Bhd — was established that year. Three generations on, the mandate has not changed: source the right product, stand behind it, and be there after the invoice.
The current chapter opened in 2013, when Optimus Distributor (M) Sdn Bhd was established in Subang Jaya, Selangor as a supply expert of industrial valves and pipeline fittings. The warehouse and offices sit together on Jalan Tiara 3 in Taman Perindustrian SIME UEP — so the people who quote you can walk to the racking and put a hand on the stock they are quoting. You are welcome to come and see it yourself.
In 2019 the company was appointed authorised distributor for KITZ Valve, the Japanese maker at the heart of the catalogue. Today it holds authorised distributorships for five makers — KITZ, Yoshitake, Pettinaroli, DFT and DTL — alongside principals Tiemme and Etelec and the Optimus house line: eight brands and 283 products across 30 categories, from quarter-turn ball valves to engineered silent check valves. What authorisation actually buys you — genuine product, with provenance you can verify — is worth understanding before you compare prices.
And because a catalogue is only as useful as the advice that comes with it, we sell the way engineers buy. We don't just sell parts — we sit down with your engineers to make sure the valve fits the service, not just the budget. How that plays out from enquiry to delivery is set out in how ordering and technical support work.

The people you'll deal with
No stock photography here. Sales, supply chain and application engineering — these are the people who pick up when you call the Subang Jaya office, pull your stock, and check your spec before it ships.











A supply chain we walk, not just email
We travel to principal factories — here at Yoshitake Works in Thailand — and sit in technical exchanges with bodies like JKR, because a distributor who has stood on the maker's production floor reads a datasheet differently.


Where we supply — and what we do beyond supply
From the Subang Jaya warehouse we supply our products across the country, including Sabah and Sarawak, and we are expanding the business into neighbouring markets.
Business coverage
Nationwide supply across Malaysia — Peninsular and East Malaysia alike — with expansion under way into the neighbouring countries.
Valve services
Supply is where it starts, not where it ends. We provide a complete range of services related to valves — including valve testing, maintenance and repair — so the product we hand over keeps doing its job in service. Ask about services when you get in touch, or see the FAQ for the questions buyers ask us most.
Put three generations to work
Send the spec and we'll take it from there — price, lead time and stock on your first message, and an engineer on the line when the spec needs a second opinion.
